only most mate, engines I rebuild I send to him for boring decking and crank machining, my hobby lathe and 3 axis drill mill just arent up to that kind of work.

I build them from there myself BUT he also does rebuild work and the difference in price between him building it up to short motor after its been machined and me doing it after hes machined it would be about negligble.

and I'll back winkle authors friend on this one... the pump will try to shift whatevers available to it if it can without the injector acting as a stopper it will pump out whats in the internal galleries.(bout 250ml total from memory)

Re Aurther's point of maybe a pushrod sticking. I dont think so, I just watched my little vid again and all rockers are moving up and down as should.....

I got a call from the Mechanic today, so I went and had a look (with camera)....

let the speculation begin :confused:

Pictures are as follow from left to right:
engine block, #2 cylinder/piston 2nd from left
#2 piston
#2 piston
#2 bore

pics of the other pistons:

#4 piston
#1 piston

transfer to head:

head, #2 second from left
#2 chamber

So forgiving my lack of knowledge, are we looking at melted piston crowns 2 and 4; especially bad on piston 2?

James.

This story just keeps getting worse :(

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?

Serg, FWIW here's a photo of the pot on that 2.8 that was overfilled and ran away in '06

and the head.

My suggestion yesterday was to get the head hardness tested regardless as I'm guessing # 2 may show up a little soft after the look of that glow plug earlier. :(

How much is a good second hand or recoed 300Tdi, just to get you back on the road and working ?

Oh Dear !

Well that's not a good look and it's time to price another new long motor I feel.
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.
