well, the intake hose is lined with oil. it's like it's got a thin layer of oil on it. i guess it makes sensse that the throttle body needs to be slightly open even at idle.pete1 said:*Some* oil in the intake is normal (everything that would pollute gets dumped in the intake -- kinda like a garbage disposal -- oil vapor from crankcase, fuel evap, etc.). If its dripping all over the place you have a problem: probably overfilled oil.
I think the gap is normal. Even at "closed-throttle" idle *some* air needs to get in.
