Does crankcase ventilation affect 83 240D oil leakage through my rear seal?
I have a small puddle where I have been parking the car. When I rebuilt the engine, I took the bottom housing that mates to the bottom of the block(the one that the oil pan mounts to...) from an earlier engine, becuase it was cleaner.
SOMEHOW I was dumb and didn't notice that mine had a hole for the Crankcase ventilation line/tube that runs from the Crankcase hosuing up about 1 foot into the Black foam covered cylindrical tank that feeds into the intake manifold.
I am assuming that this is the real reason my rear oil seal is leaking. As soon as the weather gets warmer, I was thinking of removing my pan and drilling through the bottom Crankcase housing and installing a Crankcase breather line--will this work?
