I have oil coming out my valve cover hose on a KAD43 Took it to a mechanic, they said I have excess crankcase pressure. Tested the compression and said it was fine. They then turned to the turbo, said it was the culprit and replaced it. With the new turbo I still have the same issue.
I've been told by one mechanic that didn't have the time to look at it that I should put a bigger breather hose on as this is a problem with these engines. I've also heard it could be stuck rings.
Any ideas or solutions before I have to go pay another mechanic?
