a local fella seized his 4x4 cosworth engine on the way up the hill to my garage to diagnose the problem! turns out there was a hole in his sump and he lost all oil.
he had been driving home at night and hit a big bump or something sharp and obviously put a hole in the sump, loosing all oil. for whatever reason the oil light never came on, i suspect because he changed the dash and never done it right so it wasnt working in the first place
anyway he noticed it wasnt running right on the way home and the next day drove it to my garage still not running right until the engine sized on the way up the hill to it. he said there was no boost.
we towed it up put oil in it and it was running like a two cylinder chainsaw and would hardly idle until it would eventually cut out. in all he maintains the engine was running for about 15 mins with no oil adding up the drive home and the drive to my garage and some idling in between.
we checked compression on all cylinders and all are even at 7.1/.2 bar, but the engine is still obviously fu#ked so is on the way out of the car.
question is does anyone know what are the main areas to look for damage when the engine is taken apart and how extensive the damage will be?
we,re currently weighing up either rebuilding it or fitting a replacment unit.
its a shame as it had a full rebuild a year ago in england with group A pistons, bd10 cams, new t34 ect.
