Rusty's GUIV-Upgrade

[rusty_nail]

Hopefully I pick the parts up on Thursday, so a job for Friday, maybe even Thursday evening, should be pretty straight forward... Welcome to drop in anytime mate for a beer, just call first to make sure I'm home :-)

Want a hand? I'm not busy Friday!! Would be keen to have s gander

[Rocket55]

No worries see you then :-).

[jack]

Great news Nic, you deserve some good luck.

[Rocket55]

Great to see you again Nic and big thanks for giving me a hand.

Your rig looks fantastic, never seen such a shiny Patrol ;-), let's change that soon. Your new motor looks the goods and drives really nice, and with NADS on it from the start should see you through many years of happy Patrolling.

PS: your blinkers look ace!

[rusty_nail]

so ive been driving the car fro about a week now, EGT Temps have been getting up to about 550degC, isnt that abit hot? also, Rod, mentioned that the reading may even be abit low as the sensor is tapped into the pipe near the first bend...

Is that just normal city driving or going up hills where you need to give it a bit?? might need a motor rebuild hhahahaahahaha!!
550 is getting up there for a Di especially with blocked EGR and all the Nads

nah thats driving up steep hills around my area on the highway at 100kph. hills that you def need to give it abit. it usually sits around 300degrees

edit: and FYI, 550 is the highest ive seen it get too

Did you back off at 550 or would it have kept going?

[rusty_nail]

I ran out if hill mate

[boots]

Hi Nic what is your boost reading when your getting to those temps and what size exhaust do you have ?

[mudski]

550 is high mate. As boots has asked, what's your boost reading. I got 387c on the Hume and up the big hill just out of Seymour sitting on 110 clicks towing the camper. You should be getting lower than that imo.

[rusty_nail]

Hi Nic what is your boost reading when your getting to those temps and what size exhaust do you have ?

im running the stock exhaust and my max boost is set to 14 PSI. the new mechanic changed the dawes needle valve over when he did the rebuild as he believed the current one to be faulty. one thing you have all got me thinking about, maybe my reading is coming through in farenheit? as the mcnally gauges do both and maybe one of the mechanics changed it over without me knowing???

[Clunk]

But then that would be approx 288 celcius, which would be pretty low if its working hard.... wouldn't it but i have no idea do ignore me, I'm just thinking out loud

[rusty_nail]

im going out to the car to check now

[Larx]

@Rusty_nail That's pretty much what I'm wanting to do to my 2012 GU VIII. Great outfit.

@Rusty_nail That's pretty much what I'm wanting to do to my 2012 GU VIII. Great outfit.

thanks larx, yeah i like it mate. its a long way from the old GQ's i used to have thats for sure. a very comfortable and capable rig. have you got a build thread? i would like to check it out

[Clunk]

im going out to the car to check now

Well.............

[rusty_nail]

Well.............

i cant work out how to change between f and c, but on option 3 the gauge reads C and then changed back to read mode. im fairly certain its reading at celcius also, as when i got in the car it showed 10.8 on the dial and the house thermometer was showing 11 degrees C.

ill have to take it to the mechanic this arvo and show him

[boots]

Mate drive by your gauge then and back off when temps climb. You could tweek with boost a little and get it higher but you may go to limp mode as things are. Unfortunately you need to spend more of your hard earned on a larger exhaust to get temps down to a more satisfactory range IMO.

wait so higher boost would mean cooler EGTs? is that what your saying? and yeah i know i need the better exhaust, its just choking the motor atm with the stockie

[Winnie]

Yes higher boost equals lower EGTs, more fuel equals higher EGTs.

[mudski]

Raise your boost levels until you hit limp mode, then back it off a tad to just under limp mode. You should get atleast 16psi, if not around 18...

[rusty_nail]

So if I go fucking around with the dawes and needle valve am I going to run the risk of blowing up my motor? Or is this something I can do by myself? I'm so paranoid to change anything as I don't want to go blowing up the bloody thing again

[Larx]

thanks larx, yeah i like it mate. its a long way from the old GQ's i used to have thats for sure. a very comfortable and capable rig. have you got a build thread? i would like to check it out
Once i get my tax back i'll start doing my mods. Im'm going to start a build thread with heaps of pics & when i start doing my own servicing i'll make a few videos.

The only way you could blow your motor up with the Dawes and needle valves is if you were to set the boost way too low and just drive it. Your EGT's will go through the roof, cylinder temps will be massive and you will melt pistons again. But if you were to drive with such low boost the car would under perform so badly....

[rusty_nail]

ok so i discovered a problem over the weekend. i was out 4wding and at the beginning i went to take out my tow hitch. turns out the bloody thing is rusted in their solid!!! does anyone have any clever ideas about how to get it free so it can be replaced as at the moment i can only see it being a hazard...

[Winnie]

Yeah cool, where did you go? First time 4WDing since the rebuild?
I would just keep soaking it in WD-40 and try use a hammer to knock it out, maybe use a bit of heat

[rusty_nail]

ok heat and WD40. like oxy heat or heat gun heat? lol. went to yalwal and yes first time off the tar since the rebuild. the car went great, except i damaged a rim on the way out. went the whole way out without doing any damage and then damaged the rim. gotta have more of a look as it was dark when i got home and see if i did any other damage
ill throw some pics up in a min

WD40 and a hammer flood the coupling with it and tap it to try and brake the seal it,l take a bit to loosen

[threedogs]

@ Rusty hopefully if only a steel rim you can belt it back into position.
As for the tow hitch beat it on all sides and soak in WD40, you
may be even able to put a piece of pipe or similar in from the back and belt it out that way.

As for your dawes etc I take it you have gauges fitted already, if so hard to go wrong,
1/2 to 1/4 turn at a time

yep its definately a steel rim, i was planning on belting it back into place with a lumpy and a block of timber, sound about right?

Oxy heat...

[rusty_nail]

and not dramas with the dawes valve TD, ive had it set and forget mate, the mechanic had it tuned to 14PSI on a dyno so thats where it will stay =D

hahah yeah thought so. the heat gun is so much closer tho =P

Hi mate, here's some interesting Info I read - worth a try (only found this after I threw out 5 litres of old ATF)
****************
Machinist's Workshop magazine tested penetrants for break out torque on rusted nuts with significant results!

They arranged a subjective test of all the popular penetrants with the control being the torque required to remove the nut from a "scientifically rusted" environment.

*Penetrating oil ...... Average load*
None ....................... 516 pounds
WD-40 ................... 238 pounds
PB Blaster .............. 214 pounds
Liquid Wrench ..... 127 pounds
Kano Kroil ............. 106 pounds
ATF-Acetone mix....53 pounds

The ATF-Acetone mix was a "home brew" mix of 50 - 50 automatic transmission fluid and acetone. Note the "home brew" was better than any commercial product in this one particular test. Our local machinist group mixed up a batch and we all now use it with equally good results.
****************
I think that Irish also had a post on home brew penetrating oils in the hunters thread a while ago.

Bummer about the rim Nic. Spray the hitch with what ever you have and let it do its thing, ie give it a spray each avo after work then next weekend go and find a good tree, attach a strap to it with the tongue and drive away. DO NOT USE A SNATCH STRAP, I can't stress this enough!! And don't be silly about driving off at speed. A nice straight pull should see it should just fall out.

[Rossco]

Looks like sum pretty good tracks up there Nicko. Good to see the truck back on the road doing what it loves.

I'd put a drag chain on the hitch and around a tree and drive off - very carefully of course. . . Should do the trick. Just check'n that little bolt that stops it rattling is loose yeah??

[Rocket55]

. . . .. and the pin is out :o

Yeah I checked for one but I couldn't find it. What makes me think it's rusted badly inside is when I(finally) got the pin out it was all rusted and corroded. I'll get mixing that acetone stuff!! Thanks again for all the advice!!

Oh yeah the tracks were awesome. Rocket and I will have to go for a look when the conditions are better. Rkinskey, u coming?? Todd can even be winch bitch lol

the bush puller mate haha

[mudski]

Press these bushes out is the easiest. I bought myself an eBay 12T press for around $150. I've only used it a handful of times so far but I reckon its already saved me paying someone to do it.

[lhurley]

i used a press to get mine out/ in and it made it a million times easier. I didnt have a press tool for the bush, but i pushed the center out (rubber bit) and then used a cold chisel to belt out the steel ring. Not ideal, but if your careful its fine. I does take a little while but i used what i had. I then used the press and the old steel ring to push in the new bush. A second set of hands helps. I think it took about 4 hours to do it with a mate. Only do one side at a time as it can be tricky lining the diff back up otherwise.

FWIW I was quoted $600 a side to have mine done at a shop. Cost me an arvo, some beers and LESS then $200 in parts. Genuine parts too.

[rusty_nail]

thanks guys, its been miserable and cold and wet up here and i havent had time to even look at the thing, hopefully ill get a start on it this arvo but sh!t has just been so damm busy. i would have to say that 2015 has been the year of time flying by and having no time for me.

[Rocket55]

You can say that again mate, I can definitely relate to that theory. I've still got a box of parts on the garage floor to put in but haven't managed to do it yet, and one of them is a fuse FFS!!

[rusty_nail]

does anyone the forum sell steering dampers? i would rather support a vendor from here than a random tom dick and harry from the interwebs.

i was looking on superiors website, there are so many options, i have no idea what is good and what is better, can someone point me in the right direction?

ironman are on here.

If you give superior a call they will be able to point you in the right direction.

Imo I didn't think there was a whole lot of difference between brands, other then some being a return to center and others just being standard. For what it's worth I had a efs jobbie on my car when I bought it and have since replaced it with ome and it doesn't seem to be much different. To me anyways.

[jay see]

Biggest difference I found after replacing the 18 year old factory fitted one was the steering wheel actually came back after a tight turn.

[rusty_nail]

got the wheels balanced this morning, aparently they were pretty badly un balanced. I fitted the new damper last night, and took it for a test drive after everything this morning... HALLELUJAH!!!! Wheel shakes are gone! the car feels so much smoother too without the RTC Damper on.

i also fitted some new struts to the bonnet as the old ones were stuffed and cleaned the battery terminals and sprayed them with protectant thingy. its nice to have everything working nice and good!

I have also just finished reading through your thread and have found that I am in a very similar position to yourself in that I have just bought myself an 05 model (bog standard) and am worried about exactly what has happened to you may happen to me. So from what I have read, you need to fit the NADS kit (catchcan, EGT blanking plate and dawes needle valve) and a set of gauges to "help" keep out of trouble...

Does this sound right or have I missed something?

p.s. I thought that I had a lot of patience, I tip my hat to you, Rusty

Gday mate,

so yeah as per guidance from the many gurus on here(and a few of the dribblers) i sourced a dawes and needle valve, EGR Plate and catch can from Mudski, and bought a two in one EGT and PSI BOOST Gauge from Mcnally Gauges. Even though this will help prevent the engine from grenading dont be fooled, it may still happen, unfortunately I just bought a car that was too far along and it still grenaded regardless.

there is actually a thread on here explaining the whole process, maybe someone with better searching skills can find it?

im not at my car atm but i can take a picture of where i mounted the gauge too, its quite un-obtrusive, it sits ontop of the steering wheel column.

[mudski]

These motors are far more prone to grenading if they are of the 2000-2003 vintage. Nic's is out of this time frame and he was just very unlucky for it to happen to him. You rarely hear of a motor from his model or later doing this. Very rarely. However, having said that, like Nic said, if the motor is already on the way to dropping the pin, regardless of what you do, apart from a rebuild, its going to happen. How do you tell? The only way I think would be to take the head off and look, or a compression test may give an indication that something is not right.
But don't be put off by this by all means. There are a many "Grey nomad" around, towing massive caravans with stock 3ltr Patrol and done well over 350k on them and have not seen one issue. I did some research when I had my 3ltr and have a theory on why this is so, but I'll leave it at that for now.

As you have said... " if the motor is already on the way to dropping the pin, regardless of what you do, apart from a rebuild, its going to happen. How do you tell? The only way I think would be to take the head off and look, or a compression test may give an indication that something is not right." but there is a point that I have noticed mentioned on another thread is that if the O2 sensor becomes clogged or fouled, and the boost runs too high, this is the main culprit for things going bang... Is that a reasonable summation?

from what my mechanic told me is a combination of a failing injector pump and the maf sensor being dirty look out for nissannewby, he knows wayyy more about that rahter than me

Hi boost wont kill these motors. Mine ran on 25psi boost for nearly two years. The o2 sensor your refering to. I would assume its the air flow meter, or the map sensor your meaning.

It could be a number of things as to why it happens. Each scenario would be slightly different maybe. But from the three stripped down motors i have seen, all suffered the exact same fate. Melted pistons on 3 and 4 pots. What caused this is really unknown. But thoe cylinder temps would have been bloody high for this to happen i think.

Just reads this entire thread, 2 hours later, I gotta hand it to not only rusty for your extraordinary patience , but everyone on here for their unconditional support. I too have recently bought a GU IV and glad to be in the right place with the right people on this forum! Yet to do nads but sorting out some other issues atm (possible oil cooler leak and need to fix my drivers door which doesnt want to lock). Great read, good stuff rusty.

He's gotta be a nice bloke, if I was in his shoes I probably would have lost my crap and burnt the car to the ground by now lol.

But he's right, as venting as loosing your crap is, it doesn't fix grenaded patrols!!

[rusty_nail]

does anyone know how to get the alternator out? im having trouble accessing the bottom bolts on it, is there a trick?

[mudski]

you just need to hold your tounge right Nic. Theres one bolt either side which the alternator pivots on. From memory these were a pain to remove.

Yea it's 3 bolts. I found on the td undo the bottom ones first as the top will hold the weight off the bottom 2 so they undo easier..

[NissanGQ4.2]

I helped do my dads alternator in the gq. Farken pain in the ass. The alternator that he got sent was different and the plug was on opposite sides so we done a test run and managed to get the bottom bolts in within 10 mins, everything was going to fit so took the bolts out connected the terminals on the back and proceeded 2 put it back in again.....must of spent an hour between us trying to get the back bottom bolt back in!!!

[rusty_nail]

thanks fellas ill have another look this arvo

[rusty_nail]

Haven't posted in here for ages, lots has been going on though and I just haven't had much time to get on the forum, been doing 60-90 hour weeks. The payroll is still going strong, tegan and I have moved to Victoria which some of you know and we're living it down here.

The other day I replaced the intercooler with an eBay cheapie due to the factory one leaking. The egts are much lower now and it feels better cruising, the motor has to work much less hard. Hopefully with the money I'm pulling in I'll be able to post up about a new exhaust, new Airbox and rear bar over the next few months!!
