Pulling the engine and trans out of my E30 today to do some maintenance/cleaning. While dissembling the various intake pieces, I found engine oil in them. Quite a bit in the actual cast intake behind the throttle body. The car has been running excellent and just turned 104K. I would have never known of this. Any ideas what could be causing this? Is there a PCV valve, or is my motor toast?
i had the same problem with my e21. i pulled the air box off to do some cleaning and there was a puddle in my intake so i just wiped it out i have no idea how it got there but as far as i kno it hasnt come back. i think it might have been that the intake to airbox hose wasnt properly connected and an exterior leak had dripped in, thats my only explanation
It seams these engines DO NOT have a PCV valve in them. At least according to what I'm finding out while trying to order one. Is Blow-By the only thing that causes this to happen? I don't want to have to keep adding oil, or worry about losing it.
