Basicly weaps past the seals, so need to pool over time to be visible. not enough to be visible under normal running, but given time to pool you'll see a puff of smoke, my old turbo did exactly that.
I know its been mentioned before, but finaly getting round to playing it online.
Is anyone still playing it? or point me in the direction of a decent active crew?

also stay away from anything with a mesh section in it
Sounds more and more like its had a failure before and not been repaired properly. As soon as they mention bearings it def points to previous headgasket failure and the bottom end didnt get done
