well, i go to change the oil in my wifes '04 cav with the 2.2L ecotec. i try to take the oil filter out but realize that i dont have a socket big enough for the cap, so i use pliers. then i realize i have to take the air tube out to get enough leverage. ok, np. i take it off only to discover oil pooling on the inside of the tube and in the intake. i'm not really familiar with chevy's or cars for that matter, but i'm pretty sure thats not normal. any ideas? suggestions? any help is appreciated. thanks!

 

I know in older cars that kind of oil blowback is usually a faulty PCV valve. Right off hand I don't know where it's located at on that year Cav.

 

I noticed that also on our 98 cavi when i went to cold air intake the air tube had a build up like that replaced (pcv valve) and have not had a prob since....the ecotech might be diff dont know?? try that first.

 

i'm gonna have to get a manual, cuz me looking at cars is like staring a page full of chinese letters. that would be why i have a truck, and she has the car :-) lol thanks for the help guys, i'll look into it
