Engine Smoke
I've got a 91 w/ an L98-- 70,000 miles
When I idle, there is quite a bit of smoke that comes out of the rubber hose from the pcv valve. I replaced the PCV valve, but it didn't stop. There is also an oil drip coming out of the hose. But there are no other leaks and no other smoke coming from anywhere, just there.
Any ideas??

Re: Engine Smoke (atripp)
It sounds like you have a good deal of blow-by causing too much crankcase pressure. Do a compression/leak down test and see if one or more cylinders have a compression loss.
