Problem with my Patrol

What engine and year is it mate?

Judging by the number of head bolts , piston crowns. Wiring for glow plugs and turbo I'd guess diesel.
Under 500k for a diesel....... it's barely run in

Its a 98 TD42 with 465 000 km on it

Hey dog, good info.
im well aware it needs more than head maching!
So give up on the.....
Bob is not far from me, and I have local knowledge of decent workshops.
And I agree with injector issues etc to fracture the tops like shown.
Fuel I beleive is out of whack.
Opinion only.
They come cheap

Being a DX non turbo model Bob your engine possibly has different pistons than the factory turbo models.
If you decide to get a new donk it might be worthwhile getting your hands on a turbo spec motor as they are the strongest of the TD42, followed by the silver top GQ motor (which is in my Patrol) and lastly the black top non turbo donk (yours unfortunately)
Do you run a boost gauge snd pyrometer on your rig? A must in my opinion to keep an eye on how the engine is running.
Those hills around Turondale are long and steep and I find sticking in 3rd gear and just taking in the scenery keeps the temps a lot lower than labouring 4th gear on those long slogs.

Goodluck with it mate, yell out if you need any pics from my gregory's manual :Y:

Thermal fatigue of the pistons?

Wonder if there are more cracks? Might be worthwhile hitting the heads with some dye penetrant.

Hi bob, sorry to hear your predicament. By any chance you did not accidently get some unleaded in the fuel ? Contaminated diesel with unleaded.
Diesels do not like that either.

No I dont think that I could have gotten contaminate diesel. The last 40L or so that I put in came out of jerry cans I borrowed from a mate but I know that they had good diesel in them as I refilled them for him a few weeks ago.

On further examination of the injectors the one on cylinder 4 appears to have a problem


The one on the left is off cylinder 4 , the right one is off no1.

My old cruza motor gave up the ghost about the same klms,the ringlands in the pistons were buggered,couldnt afford a rebuild,old school fella did the head for $150,barrels were ok,honed it in the chassis,new pistons and rings big end caps,cost about $6-700,this was about 8 yrs ago,it got us all over wa for yrs,sold it 12 months ago and was still goin strong,my 2 cents if ya on a budget,good luck with it.....

How's it coming along Bob?

Should be back on the road tomorrow if the injectors turn up today

The Patrol is back on the road

Took it its first run this arvo. Everything looking good at this stage. There are a few issues to look at in the morning but nothing Im worried about

A couple of minor oil leaks but they appear to be from the oil filter and the sump gasket. should be able to sort them in the morning.

Also need to bleed the cooling system

All going well I should be heading the WA around the start of May for this season hunting nuggets

Wish I was coming with you Bob to WA.

Glad you have fixed the Patrol

Goody

good to here bob, that will give bit time to give a run before u go Flatlander

What work did you end up doing mate? New slugs and headgasket?

I did a basic basic rebuilt at this stage. New pistons, rings, pins, conrod bearings, gaskets, injectors, glow plugs, oil, cooling fluid, beer , bourbon, oil filters, fuel filter.

B4 heading west I will change the thermostat and the coolant along with the radiator cap and an oil / filter change change.

It took just under 50 hours to do the job from start to finish. ............. Ok , there were a few beers along the way

Did you have the head machined, crack tested? I ask because you said you still need to bleed the cooling system.

My thoughts as well.

I have bled the cooling system and it is fine. Ive done nothing to the the head except clean it as I intend to replace it when I can afford it and b4 I head west. At this stage all is running fine, temp in stable and coolant volume is stable. No point spending money when it is not needed
