oil coming out my air filter on my 01 gt??

[01gthardtop]

So I opened my hood to do any oil change last night to find out that my k&n air filter is now a k&n oil filter and is leaking a lot of oil so can anyone help me on this one please

Severe blow-by would cause oil to travel through the valve cover vent on the drivers side and back into the intake.

Is your oil level low or anything? It would really take a lot of oil to do that. Is it possible you just over-oiled the K&N and it is accumulating at the bottom of the filter?

Also, if it really is blowing that much oil into the intake, your MAF sensor is going to be filthy I would assume, and your car is probably going to run like crap.

Your pcv valve is probably clogged, i would recommend replacing it and if you still have blowby after that install a catch can in the line running between the pcv valve and the intake.

where would I pick up one at???

I got mine off ebay, UPR makes a nice one but you can get a cheaper one if you wanted.

Usually only people with blowers have bad blowby like that, check out that pcv valve before you spend money on the catch can...
