[QUOTE=lyonsy;2707311]btw once a engine is broken in if you can see the hone marks then it was honed with too coarse of a hone and will be causing blow by and loss compression/QUOTE]
Modern diesels are diamond honed to provide the troughs without the peaks , then plateau finished, on a td5 along with others you will / should see the factory hone marks through most of the life of the engine, the troughs in the cyl retain a miniscule amount of oil to provide lubrication to the rings ( and as a by product , good sealing), if an engine runs with no oil pressure for even a small amount of time the oil squirters can't lubricate the underside of the piston to cool and lube the small end as well as ring lubrication and its all downhill from there very quickly

Really that is just so wrong what he has done and is trying to do to you by passing the buck
