Need some help from other K&N intake users out there. Pull the intake from your valve cover to your intake, and let me know if it is oily. If the intake is designed properly, there should be no oil there. I ask because I notice that mine is oily, which should not be possible since there is a check valve on the other end of that hose, which should only allow air from the intake to the valve cover, and not the other way around, assume that there is enough incoming air pressure.

 

Is your check valve working properly? I'm sure you already checked that first.

If you haven't read this thread yet i highly recommend it cause it has a lot of good info on how the VC breather system works. GMtech pm'd this to me and i found out the check valve was installed on the wrong hose.

Why & where you should/shouldn't run an Oil Catch Can (OCC) on an LNF kappa - Pontiac Solstice Forum

 

You're talking that stainless line?

No, it is not oily. Had the K+N on there 14k miles. car has 58K right now, about to turn 59

 

Yeah, I've seen that thread. It's what made me check my line. I did clean it out with MAF cleaner. I'll see if it still does it, but when I checked, the check valve was operating properly. The other line to the turbo, I don't know, since I haven't removed it yet.

 

K&N filters are great for racing. Gotta be cleaned often and oiled correctly . Dont stop a lot of small particulate. Screws up tune if the maf is not correctly positioned. Only shows gains above say 5000 rpm.
bottom line most of the K&N I see are not properly maintained. So why bother for the street?

power increase? doubtful

 

The full intake, not just the panel filter. It's critical that the tube coming from the valve cover to the intake is angled into the air stream. Learned this about 10 years ago from my old Honda days.

 

On my dsm that thing blew oil out alot more than this car, it happens, no biggy, Iv had Hahn intake to, same thing. Not much, just a bit

 

it seems to be a hit or miss. ive noticed some of the k&n intake cars with this issue. not all but some. i recommend a catch can or replacing the check valve and keep that filter clean. for a car that sees a lot of street use i like to use the aem dry flows.
