Snicko doing the NADS

[snicko]

From when I joined the forum my mechanical prowness went as far as fitting a sandflag !! Since then I have fitted a steering damper and harriette !!

Now I need to get fitted the stuff that brought me to this wonderful forum.
I have a GU 2006 ZD30 (not CDR) and already have a boost and a pyro guage fitted along with the 3" exhaust and chip.
From what I have read about doing the NADS I have questions.

Is this what the NADS consist of?
Block the EGR
Fit a catch can
Fit a Pyro guage
Fit a boost guage
Fit dawes and needle valve set up
Clean MAF and inlet manifold
Is replacing the intercooler part of the NADS or just a good idea?
Are there other things that should be done to protect the engine?

My mechanic who will be doing the job (with me hindering!!) has not done this before so is there any tricks that he needs to know?? (and thats not telling him to keep me out of it either!!)

What would be the best catch can to fit? I have looked on eBay and there are lots!
The same with the dawes needle valve. I belive in shopping locally but as America has been the only suggested place to get it are they the only ones who do them?

Is there any thing else I need to know?

cant help with other side of things

BUT......................

I HAVE TO BITE TOUNGE hahahahahahahahahahahahahahahahahahahahaha big breath hahahahahahahahahahahahahahahahahahaha

Is this what the NADS consist of?
Block the EGR Yes
Fit a catch can Yes
Fit a Pyro guage Yes
Fit a boost guage Yes
Fit dawes and needle valve set up Yes
Clean MAF and inlet manifold Yes
Is replacing the intercooler part of the NADS or just a good idea? Only necessary to replace if it is leaking, fitting an upgraded intercooler will bring the EGT's down a bit which is good for the engine.
Are there other things that should be done to protect the engine?

From the research I have done the Mann-Hummel Provent 200 is the best catch can/PCV filter.

3Bar racing is the most common place to get Dawes valves although someone on here got one fromTJM recently but I don't know if it was made locally.

Up here in New South, Nads was the greyhound on the footy show.
They had great pleasure in encouraging him to the finish line if you know what I mean.

Have to agree with Tony the Provent is the nuts guts, you will be surprised how much oil you collect. I empty mine every couple of thousand k's and I get around 50ml.
With mine I found your air filter should stay cleaner as well, but some might disagree on this one


Good luck with the mods

I need to know what has been done as its up to me. I wish I had a friend who would help but I don't so I have to pay!

Your dead right Snicko
Somehow trades just dont understand what you want done and why. And what you are going to do with it.
We all have stories to tell Im guessing.
Good luck and good on you

Had the same in my workshop some time back......lol

But that being said,.... I never knoked back anyone who wanted to learn anything about there cars either....

sorry could`nt help my self hahahahahaah

That's OK nowoolies I would do the same thing!! hahahahahaha

[fixer982]

I need to know what has been done as its up to me. I wish I had a friend who would help but I don't so I have to pay!Don't be bashful, Snicko. You need to know what's going on unless you have someone like Tony or Patch around. But you're still fun to stir up about it....lol

[snicko]

Don't be bashful, Snicko. You need to know what's going on unless you have someone like Tony or Patch around. But you're still fun to stir up about it....lol

Thanks for that....I think?.........Anyway yeah I wish I did live closer to either Tony or Patch BUT I think they are probably glad that I don't !!
When it comes to my truck I can be a serial pest!! hahahahaahhaha

[fixer982]

We have all had bad encounters with the mechanical profession and even the best ones make mistakes. If you see what they do, then when something bad happens, it's just that much easier to get the rig home. How did you go with computers? Did you get it sorted and get your remote working properly?

I would help you out S N I C K O but it seems you know more about it than i do Plus you live soooo Far away ......:( so im of no use to you either :(

Hi snicko,

Another vote here for the Provent. I’ve tried a few different types of crankcase filters and the Provent is by far the most efficient. If you haven’t got any of the gear yet, consider giving Grant at Crosscountry4x4 (http://www.crosscountry4x4.com.au/products.php?productid=274) a call and order one of his engine saver kits without the catch can. They come with a Dawes Valve and EGR blocking plate.

Then order a Patrol Turbo Boost Adjust kit from Dependable Distributors (http://www.dependabledistributors.com.au/Genquip-Other-Products/Nissan-Patrol-Turbo-Boost-Adjust-Kit.aspx?id=205&sc=43&c=3) to complete the NADS.

This gear is all available in Adelaide if you’re down this way.

Fitting the Manual Boost controller isn’t difficult, but some people have problems setting them up. If you’re mechanic isn’t sure, get him to read the bottom part of THIS (http://www.chaz.yellowfoot.org/Manual%20Boost%20Controller.htm) page.

Good luck with it.
Cheers,
Chaz

Thanks Heaps Chaz. I have the blocking plate but nothing else so I will give the guys you suggested a call.

When organising this with my mechanic I said I would take my lap top into the workshop and have your site up so if there are was anything he wasn't sure of he could read it.

Thanks again

[maphew]

Sorry to hijack the thread, two questions if I may:
1.) Can somebody explain the purpose of the dawes valve?
2.) Is the EGR blocking plate difficult to make? I was thinking of using the gasket as a template and making a plate out of 3mm plate steel?

[mcjah]

The Dawes Valve is unique to TDi cars with Vacuum Controlled Nozzle Actuators and works in a similar way to a Ball Valve, but without the vent hole to release pressure for the Wastegate. Manual boost control is achieved by bypassing the ECU controlled Solenoid Valve to have total control via a Needle Valve from inside the vehicle. The Needle Valve controls the rate of turbo spool and the TDi Dawes Valve controls maximum boost to a moderate 18psi at full throttle and 4000rpm.
This system eliminates boost spikes to over 25psi as well as boost fluctuations for EGR, which helps to maintain lower EGT's by having constant boost levels at lower pressures.

I think lol :D

3mm plate is way too thick. The original gasket is stainless and less than 1mm, so if you use steel you'd be ok with 1mm thick. If you go too thick, the flange won't line up and you'll need to undo the bottom flange at the EGR valve to get the top to mate up.

Well tomorrow is the day..............the poor mechanic!!.........hahahahahahaha

I am a bit nervous tho as he hasn't done any of this before so I have been searching on here for advice that has been given.
I can not find if anyone has put up pics as to plumbing in the Provent 200 catch can?? I got the can but no hoses or instructions came with it. HELP!!

[snicko]

Today was the day. The whole reason I ended up on this forum - Over boosting and needed to do the NADS

My mechanic was excellent. He was very patient answering my questions - Whats that?? What does it do etc............hahaha
The guys in the workshop were on there best behaviour. Until I had a piece of 2'' hose 200mm long on a slight bend in my hand! and I said this is huge!!............my poor mechanic couldn't control himself and laughed and laughed!! I mean what could I say after that????

My job was to hold the light!! and the only other thing I did was put the nut on the intercooler cover!!

We cleaned out the top thingy - YUCK

Hose fitted to boost gauge and other tingy

http://i1128.photobucket.com/albums/m481/snicko1/public/P1030134sized.jpg
Red hoses are for the catch can (pretty arn't they??)
All put back together

http://i1128.photobucket.com/albums/m481/snicko1/public/P1030135sized.jpg

After all was done we took it for a test drive. Seemed all good but the pyro guage was a bit high so need to take it back and tweak it.

Was a great day and thanks to my patient mechanic I now know lots more.

[belzi82]

Love your work Snicko, all the 'thingy's' look great!!!!

Thats about what I've been getting from my 4.2, I think thats OK for me.
Its not for your 3.0?
Sound like you are having success with your mods

[nowoolies]

well done Snicko
now you gotta go out to some distant place put the little stick in 4x4 and find out what she do`es and how much better !!!!!!
and hopfully no little thingy `s gunna fall off hahahahahaha

top job and dont for get more piccies ......we luv piccies

That EGT is to high even for a TD42...... anything under 500 is really what your looking for here. 520 to 550 is about the MAX you would want to see your Pyro hit while your Patrol is working it ding off & even then only a short burst at that.

If you see temps above 500 then its time to lift off the go pedal.

Do you know what boost your getting an those EGT's Macca?

Hey Snicko looking good, I am looking at taking the plunge with a 2003 GUIII 3L and I am trying to figure out how much it will cost to do the NADS? do you mind if I ask how much the whole catastrophe set you back? cheers

[snicko]

When I have the bill for Monday's work I will post up here what I had to pay for everything to do the NADS!! (no friends Snicko....hahahahaha)

hi snicko ha ha wont be as much as a new motor,any way theres lots of 3l running around with lots of milage on the clock
now that you have your nads done it will be easyer to mantain only one way to find out how good it is to come on over and we,ll show you some great country

Thanks Roofy I'm working on Hubby...........hahahahahaha

[snicko]

As the temp was a bit high and I hadn't had the needle valve fitted today I fixed it. My trusty mechanic used his patience again and I was back. hahaha

It's now reading 480 Degress at 15 psi full noise.

[the ferret]

That's good snicko, you must keep it below 500, over that for prolonged period will melt pistons. ouch!!
Cheers Rod.

[snicko]

Hi Guys

Hooked the camper on and went for a drive. On the flat at 100kmh 4th gear its doing 3100 revs 300-350 degrees at 13psi. (Constant speed)
At the worst going up hills it got up to 525 degrees at 15psi

When we got home the car smelt really hot.

BTW Hubby is very cross with me. The high temp melted the rubber we have on the back to stop stones when the camper is hooked up!!
And he can't see what all the fuss is about (NADS)!! So I'm copping it!! hahahahahha

[scotty83]

general question. any reason why you would take the boost gauge off that side of the intercooler. i have mine on the other side.. is there any difference in readings?

[snicko]

What are the exhaust gas temps of a standard 3LTD 2006 (non common rail) from the factory? Does anyone know?

[Maxhead]

What are the exhaust gas temps of a standard 3LTD 2006 (non common rail) from the factory? Does anyone know?

I think that would depend where you are measuring it from. post or pre turbo and distance from turbo itself aswell
Also at what conditions? towing, idling,etc...

[snicko]

I think that would depend where you are measuring it from. post or pre turbo and distance from turbo itself aswell

The workshop (not my mechanic) where I had the NADS done are telling me that 600 degrees is tops and on here its 500. I didn't get the gauges fitted before the 3" exhaust was fitted so don't know what standard temps are. Any conditions would be good.

[the ferret]

Hi Snicko, As Tony would say, keep it max 500, the book might say 600, but you know what happens to the ZD30, they melt pistons.
In a stock standard truck with no pyro, and towing a van on a hot day, temps could be anywhere.
You should aim for a max of 500 deg.
You may need to make further adjustments and Tony is the best bloke to help with this.
He'll be bound ta be back on line soon.
If your's is auto, you may need an extra transmission oil cooler or even engine oil cooler.
Cheers Rod.

[snicko]

Thanks for answering me.( Mine is a manual.) We are going away on Friday towing a camper so I hope all will be OK.

[the ferret]

Thanks for answering me.( Mine is a manual.) We are going away on Friday towing a camper so I hope all will be OK.
With the camper you should be ok, just keep an eye on engine temp and EGT's, try and stay below 500, but it will creep up on hills.
You may need to use 4th a fair bit so the turbo isn't trying to create a whole heap of horsepower in 5th.
I wouldn't go over 600deg.
Ease off if high temps are prolonged and let us know how you get on.
Have a safe trip, cheers Rod.

[Maxhead]

Hey Snicko, as Rod has said rule of thumb is keep it under 500 -550deg C.
All cars will vary but 550 is a good general "back off" point...lol

[snicko]

Thanks Rod for the tips. (I generally don't tow in 5th gear)

I hope to have some pics to post when I get back.

[Bagheera]

I have boost and pyro fitted, and haven't done the EGR block yet (waiting on needle valve and catch can arrival).

Under heavy load towing a ~1ton trailer up a long hill, boost was ~15PSI and EGT climbed to just over 1000deg F (~550deg C). This is the highest I have seen mine climb, but we're doing the Bridle Track this weekend, so I can report back on Sunday night if I see them get any higher.

will be inTeresed in your feed back thanks mate

[Bagheera]

Well we spent 2 days getting dirty, and the highest I saw it climb was about 1020-1030deg F (550deg C), and that was a long muddy hill climb in 4H with 25PSI tyres and keeping the boot down hard in 2nd on the auto. I also got to a similar temp climbing back up the winding hill at the end of Bells Line of Road, again with the boot hard in, and sitting in 3rd (OD switch off) and 40PSI in the tyres.

During the tougher track sections it seemed to hover around 450-500deg C, but backing off a little saw it rapidly drop back 100deg C in less than 30 sec.

Hopefully I'll get the EGR plate, catch can and valves set up this week, and I can see how it goes pulling the camper trailer down to Kiama and back. Climbing up Mt Ousley (sp?) could be fun!

[the ferret]

You may find your EGT's will climb once you fit the blanking plate to the EGR, but you have the guages to monitor the situation.
The temps you have reported are pretty consistent prior to the EGR block and in my opinion are normal.
Cheers, the ferret.

[Leighw85]

whats is this NADS i keep reading about?
sounds like a little bit of a problem is not attended to?
does it need to be done?
sorry about all the questions but as i have just got myself a GU 3.0ltr im trying to find out as much info as possible

[the ferret]

Easy peasy mate.
NADS: nissan anti detonation system.
The process of blocking the EGR, removing butterfly on the intercooler pipe, fitting a catch can, boost gauge, pyro (exhaust temp guage) and maybe a few other bits and pieces.
Because the ZD30 is prone to self destuct by way of melting pistons because of a design fault and other things, if you "do the nads" you will enjoy a very prolonged life of your ZD 30DI motor.
If your motor is pre 2004, I would be looking into doing the NADS fer sure.
There is a heap of info on the subject on this forum, just do a bit of a search and all will be revealed.
If you can't find it, just ask, there are a heap of like minded folk on here that would be happy to help you.
Cheers, the ferret

[Leighw85]

thanks mate.
The old fella that traded my 4x4 in at the car yard has done alot of mods to it.
I have the boost gauge, no pyro YET.
but how can i tell if anything else has been done? im not to mechanically minded lol.
NADS sounds like a must do thing for my 2001 Patrol :)

[the ferret]

Yeah, there are a few things you can do to get a good run out of your motor, first, check to see if the EGR has been blocked.
Tony "ynot" on here has posted a lot of very good info on the subject, as far as I'm concerned he is the guru and I have found no fault in his recommendations.
You need to block EGR, clean MAF sensor, inlet manifold, fit catch can, boost and pyro guages and in some cases a dawes needle valve or manual boost control.
It all sounds confusing and expensive, but by doing these mods, you can drive it hard and not have to worry about a $6000 rebuild any time soon.
As I said before, have a look around on the forum and you will find
a heap of info pertaining to the ZD 30 DI, aka "GRENADE" motor. other than that, post away mate.
Cheers, the ferret.

[Leighw85]

As I sai mate, some thing might be done already when I got it. The bloke who had the car has done a fair bit of work.
How can I check to see I anything has been done? Or should I get a mechanic to look it over?

[the ferret]

You could ask the bloke ya bought it off, and if unsure, yes take it to a good mechanic.
The EGR may have been blocked.
Robson Bros in Bentley is where I would take it as they do these mods.
cheers, ferret

[Leighw85]

Yeah I got it from a car yard. But an old bloke had it, so I don't think I could find out mate. That place in Bentley sounds good. Might have to give them a buzz! Cheers

[Leighw85]

Ok so i went to Robson Bros, and i do not have a Dawes valve for the EGR fitted. Is going to cost me about $340 to get one fitted.
also to get a Catch can fitted it will cost me about another $550 roughly.

apart from these 2 and the 2 gauges, is there anything else i should be looking at?

the bloke down there was very surprised to see my troll with the Gas Diesel Injection, any reason why?

cheers all :)

[Bagheera]

You can buy the catch can for $185 + postage. All you will need is about $25 worth of pipe, reducers and hose clamps to fit it. $550 to supply & install seems a little high.

Dawes valve is ~$70-80 (I think) and again only a few dollars in tubing to fit. If you also need the EGR blanking plate fitted, and the adjustment to the turbo screw (forget the correct name) then $340 is probably reasonable.

A pyro or EGT (Exhaust Gas Temperature) gauge is essential as many feel that excessively high exhaust temps are the first sign of problems, and this allows you to keep an eye on them.

[Leighw85]

cheers mate. I have no idea at all what im doing with mechanics hahaha i wish i could do it myself.

On the quote i got it says Dawes,EGR mod $334.50. As it says mod i wonder exactly what else they do? If it is the Blanking Plate and turbo screw.

[Leighw85]

ok so i got a detailed email today about what the bloke is going to do.
Fits a dawes valve which controls the boost.
They said they preset the max boost to 12-13psi.
Insert a plate in the EGR pipe which restricts the flow of exhaust gases.

sound right peeps?

[the ferret]

I would install a PYRO gauge as well, and NO hole in the EGR plate, fit a catch can while yer at it.
Cheers. ferret

[Leighw85]

Yeah thanks bud. That's all on the list to get done aswell. I don't think I will get them to do my gauge as they say they prefer not to for some reason, and I think they tried to steer me away with the price they gave me. $250 to install a pryo.

How hard is it to do myself? Do I drill a hole in the exhaust and run the cable to the gauge, aswell as the ignition wire from the boost gauge already installed?

Im a little strap for $$$ at the moment after just buying my baby, so what should i be doing in order?
gauges before or after the mod and catch can?
Thanks all

Hey Sniko how has it been going? have you managed to get your EGTs down? ifso how did you do it? Cheers

[snicko]

Hey Sniko how has it been going? have you managed to get your EGTs down? ifso how did you do it? Cheers

Have a report for here but I am at work at the moment so will post up where I am at with the temps etc tonight

[snicko]

After doing the NADS we went on a camping trip for 10 days and the boost and temp readings behaved themselves but the fuel economy was terrible.

As we have a chip fitted I think its over fueling and my mechanic is new to all this so I need to take it to someone who can take the guess work out.

The only time we got the temp up (500 degrees) was punching directly into gale force winds going up a long steep hill.

Bit hard to see but the temp gauge reads 305 degrees with the boost at 13psi doing 105 kmh pulling a camper trailer in 4th gear. The temps ranged from 250-350 depending on the road conditions.

[snicko]

UPDATE....

My mechanic had set the dawes valve out to max and the needle to 1/4 turn.
He seams to think it might be the chip that is over fueling so at the moment I am doing a 200km fuel test as is then do a 200km fuel test without the chip.
I have taken some more pics as the other ones did not have the needle valve fitted.
Also the catch can is now secured so I took a pic of it too.

OK more updates!!
October
The fuel test came back = 10L per 100km (Troll was empty with 100km around town and 100km on the open road)
November
Went to the Vic meetup with rooftop tent on with plenty of gear in side. The four fills were 13, 12, 15 and 13km per 100km

[snicko]

Just come back from spending some time in the big smoke and spending more money on the Troll. Hubby let me go by myself BIG MISTAKE!! hahaha
Met Chaz who took a look over my NADS and found the needle under the dash wasn't working.
Would work when checking individual hoses but when all put together didn't work!! What the???
So he ended up putting it under the bonnet and it works now! (Still need tweaking tho)
Chaz seems to think its either the wrong hose was used or the length is too long. (family forum now!!)
Got to have a ride in Chaz's Troll!! Now that's one awesome rig!

Also look at my latest investment!! Got the boys at Cross Country 4x4 to fit it.

Hey snicko, Was just wandering which hose that your boost was plugged into?? Looks like a different one to where mine is

Yes, something prudy to polish............oh sorry....do you mean does it make the Troll go any better...hahahaha....yes the temp behaved it self on the way home.
Our ultimate goal is to tow a van and this is where it will come into play.

[Chaz]

Hi snicko,

Very nice job on the cooler. It should certainly make a difference with van in tow. Your rig is shaping up to be one very capable (and good looking) unit that will hopefully go the distance.

Just need to do something about those Coopers……………….lol, sorry!

As for the Coopers, tyres wear out and when I get what I want the Troll will be finished!! (Oh and I haven't convinced hubby yet either!! hahaha)

Hi snicko , must have missed this post about your mods . Thankyou , top pics and interesting. One thing that stood out to me was your provent install and the plumbing , looks as though your hoses are fitted wrong to me .should be ? top is inlet / bottom outlet , just double check ? there should be an arrow on the body for direction / flow .

Would it still work if the hoses were the wrong way. So far we have got 60ml out of it.

[boots]

If its working for you , then all good I reckon . how is the filter looking ?

Do you mean the air filter? Haven't actually looked so will have a look tomorrow.

[Chaz]

I just noticed that, well picked up Boots.
It will still filter the fumes before they go through the intake, but the pressure relief valves won't be working the correct way so you'll have no safety backup if the filter gets blocked or the system becomes restrictive.

[boots]

sorry for the late reply snicko , the provent filter element is what I meant . sorry for the confusion .

Took me ages to gather the info, get the bits and then get them fitted. When you start post up a thread of your progress as everyone has different experiences.
Look forward to reading yours.

[Yendor]

Hi Snicko,

I was talking to two blokes on the weekend, both had cross country intercoolers fitted and both had problems with the metal plate that is fitted under the bonnet for the scoop, rubbing on the intercooler (back passenger side).

Might be worth checking yours.

Cheers Rodney

Thanks Yendor for thinking of me I will go out and check.

Did the guys say how many km they had done since the intercooler was fitted?

I read somewhere that with a bigger intercooler the scoop needs to be replaced and the suggestion was the one off the Holden Rodeo.


EDIT:
Just checked and yes mine has small rub marks in the same spot.

Looks like I will have to do some more research into a bigger scoop.

Thanks Yendor for the heads up .

[Yendor]

Sorry I don't know how many Ks they have done since being installed.

I know one has only just been installed and it didn't take very long for it to wear a flat spot in the intercooler.

They both run standard scoops.

One guy removed the plate altogether and the second guy glued a strip of rubber/foam along the edge of the intercooler.

Lets un know how you go.

Cheers Rodney

[Forest1970]

Hi all, just new here, where will i find some installation info here for NADS, I have a 2006 GU (Does this make it a series 4 ?), Direct Injection, Auto trans & pretty much stock at the moment, and does my model still need/benefit having these mods done.
Thanks in advance for any info..

If its the 3ltr then yes you need to NAD up.
What you will need :
* Dawes : From the US or me, I'm a bit dearer but its a lot quicker
* Needle Valve : Dependable disty's in Adelaide
* Provent 200 catch can : Ebay The $170 priced one.
* EGR Plate : The Ferret does'em
* Pyro bung : Zorst shop
* assorted hose and fittings : Hose shop
* Boost and EGT guage (this needs to be fitted before anything) : Anywhere you fancy

[Drew]

Any updates on your travels with finding a bigger scoop snicko ?

[threedogs]

Just recently fitted NADS to my 4x4 with Forum help {thanks} You'll find your EGTs will go down if you increase boost.
Max around 18 psi, Boost controls the EGT. If you can't acheive enough boost you may have to stretch spring to up
the boost.

[Winnie]

That looks like it would suck the crotch out of a low flying duck!

[threedogs]

Yeah can really feel the difference, just upset my intercooler not leaking yet, would like to feel what happens with the larger IC.
Pricey but well worth it IMO. 4x4 was a slug [normal] when I took it off to be sprayed, LOL
WRX scoop look ok too, you might find the modded 4x4s get heat block, as the heat can't escape from the engine bay
Chances are if you have a GU with a bullbar the scoop doesn't work.
see the front vane inside large scoop.


Pass the duck I'll give it a go lol

Is this one of those 5 in 1 threads you hear about??

[Sir Roofy]

[Drew]

Not if you're the duck...or flock in that case :)

I think I missed it, which scoop is that ?

[threedogs]

go back 6-7 posts

[mudski]

I think he's referring to. Where did you get that scoop? As I'm keen to know aswell. Something i need to do before summer hits. That and a thermo fan for it.

[threedogs]

Been thinking of a thermo fan, asked the question here before and most were of the opinion
not really worth it. MUDSKI I'll PM where to get the scoop not far from you.


A fair bit of work has gone into these scoops, they are designed by a Turbo freak.
The internal vanes direct air to the front of the IC, where as an OE scoop all air goes to the rear of IC.
Meaning this IC will work at a lower speed possibly around the 60kph mark, where an OE
does nothing till 80KPH.

bullbars redirect the air, ever seen a moth or similar go into the IC ??????

This same person, turns your vacuum turbo into a pressure system there for eliminating
Dawes and needle valve, boost and EGT guage still required

[Drew]

Psst pm me too pls :)

Thanks for the info mate. I think for the price of a thermo fan, it wont hurt to try one. As for converting the Turbo from vacuum to pressure. I heard thats quite expensive and using a dawes and needle valve seems to work well anyway...

[Bagheera]

I'd be interested in where to get that scoop as well.

[Forest1970]

Thanks Mudski, I get most of what you've written but whats Dependable disty's in Adelaide, and do you have a website or something to check out your Dawes Valves for sale, thanks heaps for your advice., Also is there somewhere on the forum that shows from A-Z the fitting of all these things? The post from Snicko is pretty good, just wondering if there were any others? Thanks again

Sorry. Dependable Distributors they are called. Disty for short. The Dawes valve I do sell myself but I have ran out. I sold 10 in 9 days, quicker than i thought. Five on Ebay and five through word of mouth. I have more coming but it wont be for atleast a week or two I reckon. I am dearer than getting it from the states but when I had them, you would get it much quicker that waiting for it to come from the US. I'm in the process of a fully adjustable Dawes type valve which has a screw cap on it to adjust it, rather than using two spanners...
Which fittings are you referring too? The fittings for the Catch can? Or everything? What model Troll do you have aswell? I'm happy to help you out where I can.
Food for thought, the gauge I have is from McNally Electronics. Its an electronic boost gauge with with a digital EGT read out on the same gauge. Sits nicely right in between the speedo and tacho.
http://www.mcnallyelectronics.com/

Derrr! Don't mind me. been a hard day at work today. The fittings you asked about, you want to know how to fit it all.
First thing to do is get the gauge and installed. As you need to see whats going on when you fit everything else. Getting the pyro fitting in the dump pipe is the biggest pain for the whole job as you need to remove this pipe, so this means having the truck off the road whilst you get this done.
Then you continue with the rest...

[threedogs]

X 2 with Mudski, choose what gauges you're going fit be it Mc Nally or Pillar pod style. No point doing any other mod till this is done.

You need to see whats happening as you do mods and can adjust as required as you go along

[Forest1970]
