Threedogs motor thread

[the evil twin]

The hose split along almost its entire length and as it happened just as I was entering the town I coasted into the garage and the mechanic took over from there. Lucky it happened where it did or I would have had to muck about with it to get it going, or use my RACV total care to come to the rescue.

Just sayin' for future issues or for others...

Any hose same dia will do, you can even chop up the 'outlet' hose if needs be
Thats also why I carry a couple of inches of offcuts in my emergency kit

This new fangled idea where the water circulates continuously you need to block inlet and return

Old school was even easier, just loop the pipes or turn off the heater tap you only had to block the return.
An EH Holden I had went for months with a whittled down piece of gum tree branch as a bung when the heater core split.

[threedogs]

Ha Ha,,,have you seen the "stuff" that comes out of a blocked EH heater core yuk lol

The girlfriend sure did... dunno why I got the blame I wasn't wearing the white slack suit and she was the one who turned it on.

I mean to say when something hysterically funny like that happens it takes a while for a bloke to stop laughing.

Ah well, it wasn't meant to be, no sense of humour, fantastic set of t... uuummmm... toenails but no sense of funny at all

[mudski]

Or carry a couple of blanking caps better still fit a couple of taps on the outlets might even make the air conditioning run a bit cooler
Or keep some 5/8 barb joiners in your tool box...
Ive been thinking about running a heater tap on my GU, somewhere, so when the temp control is set to cool, the tap will just close off the system and recirculate the coolant through the tap. As im not sure if there would be any detrimental affect to just blocking the heater hose.
Having a heater tap would solve the warm air issues with these GU's i reckon.

Yeah... pain in the rrse isn't it.

[Kimbo63]

Can't see it having any effect on the cooling system having two taps on the hoses where they come out of the block turn off in summer and back on for winter we did this to all the excavators made a big difference to the performance of the aircond

Suffered with this too, fitted an electric valve in the heater water circuit. It doesnt effect the cooling system at all.

The warm air still enters the cab! it comes from across the bonnet into the fresh air grill where the wipers are.
At speed its not a problem, but slow running in the bush or traffic the warm air above the bonnet is the source.

[the evil twin]

So what was the actual original problem?


Started off with Sub Tank Warning Light was on all the time...

Using a logical fault-finding technique to make sure we don't miss anything we are working our way thru the alphabet.

We have got to 'R' for Radiator so should have it sorted in under 300 posts if all goes well

Only problem on the horizon is when we get to 'S' for Sarcasm (bloody dirty thankless task that is so not looking forward to that at all)

[mudski]

Any updates John? How are the temps? Any more water leaks?

[threedogs]

Heater hose burst again today,other end he he,,, so patched until I pick them up tomorrow,

After that Ill be happy temps are 88c max with my driving.
after a week or two with the new hoses Ill fill with a decent coolant

[threedogs]

I also replaced the metal tube that goes around the back of the motor,
with some 5/16th copper tubing,

That goes to the egr valve. You probably could have just looped the hose back.

Hey John did you back flush the heater I know been awhile been
visiting the other side where you go HHHHaaaa was in the shower
so I'm told pressed up gainst the wall enioying what I thought was a
hot shower going down my back NOTbut was feeliling good
vituial shower unfotunatley scared Jane

[threedogs]

Nah all clear hoses only came in today so after I drop off lily
Ill grab the hoses and fit them at TJM. I need to pick some
stuff up at the laser cutters too

[threedogs]

Drove to CBC Airport West to pick up two heater hoses $103.40,
water dripping in the car park, no big deal the hoses were getting
changed anyway. Topped it up and drove to TJM only 700mtrs ,
parked around the back and changed both hoses, for anyone with a ZD30
I would think of a way to insulate them a bit better, maybe some exhaust wrap.
They are very close to the turbo.
Anyway topped it up with water and I had water pouring out from underneath.
Its parked at TJM till I can figure out how to get it home. looks terminal
Ive tried to patch but I will just sell it now,, absolute cost for my mate with a new head to fix is
a few grand as apparently there is a lot of labour involved in pulling out a ZD30 then
stripping it down, not sure what Ill do .but looks like Ill try and sell it and get what
I can , bummer I love my Patrol,,,oh well we'll see

[Winnie]

Where was the water coming from?

[threedogs]

Too much pressure looked like the thermostat housing area, flowing out at a great rate
Ill have to wait see till it gets back here, when ever that is

[Winnie]

Can your mates at TJM there have a look at it for you?

[threedogs]

Nah mate they only fit accesories there,
Was just reaing 4x4 EARTH and some guy is saying if you block the EGR
pipe on a ZD30 all will be good, Dont agree with that statement at all..
Ive driven 220k and pretty sure its gone now, just a matter of waiting
till I can get that Nissan mechanic to look at it,,,,busy man
Bugger really as power was still good, Damn damn damn

[4bye4]

TD, didn't you just do a repair to the thermostat housing? May just be an unsuccesful repair. Better than a new head.

[threedogs]

We used a housing from another motor plenty of RTV bolts went in easy.
I really cant see how it would leak there Mark did it by the book.
You can tip water in and when it gets to a certain level it just pours out.
power is still great

[Hodge]

John as much as it may sound hard for you to do, financially etc... Right now you seriously need to think about taking it to a shop and getting it looked at properly before maybe doing more damage to the motor and/or your own mind , otherwise it'll drive you mental.

Right now I would not have the faintest idea as to what the problem is or what the original issue was...

Mat has mentioned numerous times to go get a simple coolant gas test done , this will potentially show an issue ...

It's just getting ridiculous now.

[threedogs]

It looks to me if you look at the picture there is a small rubber hose
I just think at this stage all my hoses are failing and in need of replacing
as in a major service etc
I can't see how the thermostat housing seal could fail, so im crossing that off
so when I get the Patrol back Ill need to remove the top shroud and remove the alternator,
and then the thermal fan....replace that stupid 50mm piece of hose and assemble it all again.
That hose would have the be in the worse spot ever IMO lol

By 2 as it is going round and round in Circles

[threedogs]

If you drive a ZD30 with 200k plus on the clock
Its time to change those two heater hoses .
What happens with the heat generated by the turbo
directly underneath, is the hose seperates into a inner
and outer hose, either wrap in some exhaust wrap or by some Gold tape.
Or change them before your next trip, especially that 50mm job

[jay see]

This all seems odd.....

I had a problem that made my temps run up as high as 105 degrees, turnout out being the radiator cap. Building pressure with caused it.

You say that it was maxing out at 88 after the last time it as put together, now it has water pouring out.

Could it be another hose or something else. I'm not familiar with these engines. Is there any other water hoses on that side of the motor?

Edit.
There is, John posted while I was typing.


As I and a few others have said, save yourself a lot of unnecessary worry and expensive and try to get it over to a shop and get it professionally looked at before you do anything else to it.

Not a having a go at you John, just trying to get you back in that seat that you love so much.

[threedogs]

There is a small hose that has split after
I repair that Ill get my mate onto it.
I need to be mobile, bottom line

Just so no one else asks I WILL be getting it tested.
but first I need it here not 20ks away.
Then repair that hose so at least It will be running to test
I acuatally lined up the mechanic last time it was apart
Yet I can drive to the city and back with no dramas.
Oh well

Make up your mind John. Is it coming from the thermostat housing or a split hose?
This thread makes my head hurt.

[mudski]

Hoping it is that small hose. If and when you get it off check the steel pipe for corrosion. Going by the brown colour on the inside of your hoses when i was there. It wont surprise me if the pipes are corroded.

if not the owner it was his off sider. why do you think I never go there anymore
wouldnt take my lawn motor to them.

I may have brown in the pipes but I dont think any well hope not are corroded

Winnie unfortunetly I dont have xray vision like you .How the hell would I know where its leaking from
wierd question Ill need to remove a few bits and pieces first to get to the area
I scanned a photo of the motor and I assume its coming from that hose.give or take
Sorry about your head hurting, may I suggest an Aspro and a lie down.
Mark knows how hard it is to get into these motors. Im getting the Patrol
tilt trayed to my place tomorrow and will pull it down over the weeekend
if any one feels like helping that would be great, not a big job just fiddly

Great post too Winnie real helpfull, i can use thermostat housing and split hose
Nope cant use any others LOL LOL LOL

[macca]

I admit to not knowing a lot about these engines, for you to keep blowing hoses etc there must be a pressure build up.
Main place to get that sort of pressure is from a pot? Reckon there is a head gasket or some other passage allowing pressure in the cooling circuit.
You seem to be like a cartoon character who has run out of hands trying to plug the leaks, stop one and another starts.
Not much help I know, just feel you are not in the right area to find whats wrong, fixing the result not the cause.

[threedogs]

As per a previous post so the same thing didnt post again the motor needs to be running for it to be tested
also from a previous post Ive lined it up to be tested once its going, So again Ill tilt tray it home tomorrow as per a previous post
repair if possible whats leaking as per a previous post and then get it TESTED, I cant be any clearer than that, lol
No doubt others will ask the same thing lol

[taslucas]

Yeah I'm very confused trying to follow this thread too.
So is it getting hot and boiling over which is then pushing out the coolant (water) or is it losing the coolant (water) and therefore getting hot?

When the thermostat housing repair was done it wasn't leaking from there but now it is. Would that mean that if there's a leak there its coincidently gotten a lot worse in a couple of days?

You said it's coming from the thermostat housing but are going to pull bits apart to get to that little hose.

Surely if you start with a dry engine then get a torch and watch closely (even with an extra set of eyes helping) you should be able to zone in on the leak better?

It's been losing coolant (water) for a long time but hasn't been losing it from the thermostat area until yesterday?

Also, as you've been keeping a very close eye on any slight degree change in temperature, I wonder if there's a discrepancy between water vs coolant? If it had coolant in there would it be reading the same temps?

As has been said above, even if money is tight you should really get a few tests done by a professional.



>>>tappin from tassie

[threedogs]

its coming from that area again I dont have xray vision.
I doubt its leaking from the TS housing only that area
again with a torch and xray vision turned off it seems to come from the area
above the TS housing or there abouts, with xray vision turned on I couldn't pin point
to an exact area, AGAIN when its running its getting TESTED professionally.
better turn my xray vision off sons girlfriend just walked in lol

[trekster]

So im really confused over all this,

You convey yourself over the forum as someone who has alot of knowledge about patrols yet its really only about nads more then anything, but this problem seems to be a big witch hunt.

I'm not sure if tou fall into the knowledgeable category or more into the chick category who drive a vehicle, put fuel in it then when something breaks are unsure as to why...

You say you had work done and by the time you found out it had water in it and not coolant it was too late, how many kms was this? 1,5, 50k km? If it was more then a 1000km then that shows you don't maintain you car well enough and only have yourself to blame for all this.


I honestly see you as having 2 realistic options here:

Take it to a mechanic tell them whats going on and let them fix it properly,

Or

Sell the patrol, buy a toyota corolla which go forever and be done with the whole "modified vehicle" scene as it doesn't seem to suit you.

Fair go John, you are the most "known" here. Commenting on everything gets you out there.
Your crossing paths comment is ridiculous.

[Bloodyaussie]

For your own sake john just go and get your cooling system at the very least pressure tested....

All this guessing and stuffing about may well be doing more harm than good.

I said at the very start that the whole subject is confusing and incredibly hard to follow with no real procedure in place for diagnosis. .. having the odd person pop around to help out here and there seapping this or changing that is not the way to go at all... just get it tested at a qualified mechanic.

His water leak is from a split hose. A tiny, pain in the arse of a hose and spot to get too. One of the pipes that run along the side of the head, for the heater, joins up down inside and below of the thermostat housing. Couldn't be in a worse spot.

Still believe that you need to get it to a shop and let them give the whole cooling system a once over.

When you get it there (a workshop) if you need a ride to get back home or to pick it up yell out.

Would hope not!

Lower my boiling point was what I meant?

Your boiling point couldn't have been lower thus far mate. You want it to go opposite.

Actually made it to the laser cutters and then the powder coaters and back with no dramas.
At least now I can get some orders out. lol

did you notice a change with the lower boiling point? is it still loosing water?

[threedogs]

No,, what Ive done to remain mobile is Ive cracked the radiator cap to let the pressure out.
As it is I'm not losing water or is it getting hot, How long it will last like this is anyones guess.

you should try leaving everything as it should be? like the cap on properly etc, maybe the head isnt as bad as you think

[threedogs]

Cant drive it 200 mtrs with the cap on, it will just boil straight away.
As it is now it stays at 88c and lower
lets wait till its tested lol

[rusty_nail]

it will just boil straight away.

what makes you say that? has it happened?

[threedogs]

Cant drive anywhere with the cap on, builds up way too much pressure.
I drive it sparingly, and wait for test results

[Sir Roofy]

Ive done over 100k today without any hiccups, Ill more than
likely see Andrew at On-Track saturday morning if he's open.
I want to get the coolant in it to lower the temps a tad more
Good guess its 60k on the button to get there

What happened between here and today you did 100ks no dramas
but cant drive with out the radiator cap cracked
If you drive with the cap loose you'll lose coollent anyway

[threedogs]

I havent lost any "coolant" with the cap cracked

I know that you said that you have a new cap, but it sounds like it's not working properly????

So is it getting hot then boiling and therefore pushing coolant out, or loosing coolant first and therefore getting hot?

[threedogs]

its going Im mobile locally so wait till I get it tested
its obvious something is stuffed big time, a test next week
will end speculation, so Ill leave it till then

[Winnie]

I think you should get the engine tested.

Yeah, and get the Cap & Coolant tested at the same time

As suspected I have blown the head gasket between the water channel and the compression chamber.
That is why the cooling system is pressurizing,
I have not blown the gasket between the water channel and a oil line , as Id have water in oil
which I dont.

[jay see]

Did you get the head off John?
If it's only the gasket you should be able to get away with getting the head re surfaced and new head bolts.. Where did you end up taking it?

[Touses]

It's not losing coolant? Hmmm. But it is holding residual pressure for a while after shut down? Hmmm.
Sound like it can only be one of two things.
Radiator cap kaput or maybe wrong pressure rating.
Small leak in head gasket. Have the same trouble at the moment.
The constant overheating bit is troublesome. Water pump.........?

It's never normally just the head gasket. You can almost guarantee the head will be cracked.

Yep 100% agree. I would be lining up a new head without question.

[threedogs]

If the gasket had broken else where I would have water in the oil.
Its not cost effective to replace the gasket Ive had quotes from
$6k-$10K , Cheaper to replace the motor as Mudski said

Dont you think its a motor out job to replace the head
then you have to changeover most of the gear, probably
a bit of machining I dont know

No. Can be done in situ. Sure it would be easier with it out but no machining required.

6-10k to replace a head is crap. More like 6-10k for drive in drive out engine replacement.

For someone who goes on about being in the industry ypu surely could get the head replaced for 2k or less. 3k at the most.

I've done it before on a surf, at home and for under $2k new head and all bits and pieces. Then I was told that my overheating was due to a crack in the block. Got a reconditioned bottom end for $3k and it still overheated, then I sold it.

Sorry mate, but I really don't know what else to say.

This is why I didn't want another diesel, especially one that is prone let go.

I'm happy with my gas blower, cheap to run and strong as nails.

I admit to not knowing a lot about these engines, for you to keep blowing hoses etc there must be a pressure build up.
Main place to get that sort of pressure is from a pot? Reckon there is a head gasket or some other passage allowing pressure in the cooling circuit.
You seem to be like a cartoon character who has run out of hands trying to plug the leaks, stop one and another starts.
Not much help I know, just feel you are not in the right area to find whats wrong, fixing the result not the cause.

Lucky guess...
At least you have found it now.

@ Jaycee no its not at a shop and nor is it pulled pulled apart.
I think a ZD30 would be a tad more complex than a surf engine
again I have no idea, but I cant see the comparison motors or 30 yrs apart lol

First up John, it's jay see and how did you come up with the conclusion that you have a "blown head gasket between the water channels and the compression chamber"

A turbo 4 cylinder is just that, they may have things in different places, but having working in a Surfs engine bay, give me a Patrol with a ZD30 any day.

Just wait till my powerball numbers come through, I suppose lol

Why do ppl always take things the wrong way.

The diagnosis was done by Frank from Mr Cylinder head
who works on ZD30s day in day out, I have no reason to disbelieve him.
Other advice and tit bits came from Mudski , Chaz , Andrew from OnTrack,, Kealba and
Paul from Outback 4WD in Bayswater.
What's done is done Ill now nurse it till my numbers drop, Don't really want to sell it
just because the head is gone. PM sent MN

[nissannewby]

So I just did a quick look for parts. $1836 for a new genuine head assy and $195 for an engine gasket kit. This is all genuine parts to dont forget. They are also prices any man and his dog can get as well. So I dont know where you or these other shops are getting 6-10k from.

I'd be first removing the head and checking everything else. Cracked pistons etc etc. Last thing you'd want is to put on a new head then later on it drops the pin in a cylinder or two.
FYI, when my pump failed on the ZD I was going to just put a new pump on. Then I go the green light for the conversion. My old motor was stripped down at the workshop and they found number 4 piston was cracked. Even though the inside of the motor was spotless due to my strict oil change regime and the motor still when really good... So If I have spent the 4k, or what ever it was, on a new pump, it was only a matter of time for that motor. And it would have been 4k just shot down the dunny.

Just saying.

[macca]

Without going back through all these posts, a question.
Why did you put that copper stuff in the cooling system, did you have an issue with the head before?
I don't understand all the to-ing and fro-ing when there probably was a pre-existing problem that you knew about.
Just seems like a good starting point of the diagnosis that was ignored, or have I got the wrong end of the pineapple?
Nearly a month and 400 plus posts, must be doing your head in. Good luck with the power ball, I'm told you must buy tickets first... bugger.

4k for fuel system replacement then a 4-6k rebuild would have still seen you ahead of what it cost for the conversion though.
