2s been over heated and does not provide a definitive answer it could have been done from overglowing.
the rest look like normal combustion conditions.
Well if my truck was just a toy or farm basher I probably would tow etc to try and start it. Then again, I probably would have just pulled it down by now, learning as I go. Unfortunately, with the $$$ I payed for this NEW engine only 2 or so years ago and it being my source of income, I dont want to f@#k it up more than I already have.
My uninformed, crude thoughts on #2 glow plug is, that if there has been enough heat to do that, what else could be wrong in that cylinder, ie piston etc....
Turning it over to tes a few things is probably not going to do much more damage, but towing it around untill it fires could result in a scrap heap.
Oil ingestion normally results in mechanical damage (hydraulicing) rather than thermal. You get lots of smoke because the oil isn't atomised well (comes in blobs, rather than a fine spray) but it doesn't produce much heat.
The reason behind towing it, is the cylinders build up more heat and compression pressure than they can by cranking with the starter. So it can start a stubborn engine where cranking just endangers the starter motor.
If it turns over freely already I don't see it causing any damage. Provided you've stopped the oil source.
Hi All

well the only basess of oil source I have, was the level on the Dip stick being high (15mm or so higher than max mark) after oil change, the fact I have dropped out 2 litres and that now the dip stick shows just under max.
I removed all the intake plumbing and thougherly cleaned it, including the intercooler.
I have not checked the turbo.
I have replaced the lift pump. (it was not pumping due to a bent arm). Whether or not it was leaking into the sump is questionable, but with the evidence so far Im leading towards it wasnt.)
I have now figured that since my engine is different to the 300tdi that the lever arm on the lift pump only gets 1/3 of its range of movement, therefore not enough to manually pump fuel. I have seem a photo of another 2.8 being fitted into a defender. The lift pump did NOT have a manual lever. I belive this engine to be a new factory supplied unit.
my concern is a bent rod or stuffed rings and fear that continuealy trying to start it or starting it will lead to futher bore damage?
