How much does a head cost Serg? Do 300Tdi heads fit? (hopefully the head is still good though... but you haven't had much luck lately...)

And do OS Tdi pistons fit???

Sorry to see this Serge :(

I haven't had time to look at all the posts here.

Until I saw the last few posts I was thinking overfilling to that extent shouldn't cause this and it had to be something else. The oil level near some cylinders will get much higher when offroad on ledges, steep slopes or side slopes.

I need to look at the thread more carefully and have to go now, but suggest getting someone to test No 2 injector.

James.

#2 is the problem, or result there of. Numbers 1 and 4 were shown as a reference and to see if any would say they were bad or good. Our judgment is the rest are good (at this early stage)

remember the truck was only dropped off this morning. Early days yet.

Sure that's not a ZD30?

How do you overheat just #2 enough to melt the piston and grab the bore? I figured that cylinder would be one getting the most air. How are the valves?

hey Ill ask the questions around here.......your ment to be one of the ones that can answer them :p

valve and head pic attached on previous page. Head is going in for a full check up.....time will tell.

There's a bare 300Tdi head in the Markets. It's flat, compared to Serg's which has slightly spherical combustion chambers.

What do the others think? But I would say that block would be a worry as well.
I think that if it was mine I would sell that motor off to get back some of the costs and get a new motor with a new turbo as well. How's the money tree going?

Those pictures certainly do tell a different story, too much combustionable material has found its way into that motor, number two cylinder, being the one that copped the worse of the oil from the turbo seal failure.
The EGT would have been high, with that I'm going to fit a EGT device to my Defender now.
.

I think that the block should be ok....a guess but nothing leads to say it is bad. The engine is 70k old so not really old. It has been well looked after otherwise :eek:. The cost of any decent new motor would (hopefully) be well above repairing this one (read double) It would be very hard to source a new 2.8tgv, so I would be back with a 300tdi (which I really really dont want!) Plus a 300tdi would need some custom work as custom work has been done to fit this engine = more money for a new engine.

Turbo seal has not been rulled out but I think it to early to say it was the problem. Yes it could be ****** now, but that could have been a result rather than a cause. The lift pump is in the same boat, but leaning to a result not cause.

DEFINITELY fit and EGT, regardless of engine stock or not, etc. It would not have changed this outcome, but it certainly has helped others avoid engine failure or damage.

Thanks John, I would be very interested in hearing your thoughts. I realise your internet time is limited so dont stress if you cant get back for a while, but please do get back when you can.

I only said to Rick today about the stock max oil level getting higher at angle when offroading. The only difference is what offroading I have done is mostly low speed/RPM stuff so the crank would be throwing/sloshing less. My engine has the standard 2.8tgv sump, NOT the 300tdi sump.

It was approx 15-20mm higher on the dipstick when read just before the drive out to "Death-by-oil" rd (dipstick is also the original 2.8 set up)

all 4 injectors and Injection pump will be tested. We figure #2 is stuffed, but, once again, that could be result not cause.......

------I had it towed home. I removed the intercooler and all its hoses and cleaned them out. I got about half a cup of oil out of the bottom hose and about half a cup out of the intercooler. The intake hose from air filter to turbo had some in it but only a table spoon or so. The engine breather line was very oily and the bottom of the airfilter has oil on it.
Edit: forgot to add, engine is a 2.8tgv, very similar to a 300tdi

Reading this post again and putting the last information supplied together.
The oil may have come from the breather where it feeds into the air intake hose or the turbo seals, either way it has caused a runaway motor.
Those pistons have been too hot and that number two cylinder would have got the worst of the oil.

I rang a NZ mob today that use to do 2.8 conversions, but they no longer have parts. Im waiting to call M&D in the uk to nut out some prices.

2.8tgv is 93mm bore, 300tdi is 90.47, so at even 50thou over bore the tdi would only be 91.72mm
