What would cause this? Is my crank case pressurizing? Could it be soming as simple as a PCV valve, or is there a bigger problem? I noticed that the breater filter on my valve cover was coated in oil yesterday, I am wondering what would cause this. This is on my 98 Supercharged GXE. Thanks for any insight.

 

Thats normal, but too much can be a bad thing. Normally its connected to the intake duct and gets burned. Thats why there are oil separaters stock. You should clean the breather, then monitor it to see how much builds up. Then youll know if you have a problem.

 

Supercharged? Hummmmm.....
Try changing the PCV (POSITIVE CRANKCASE VENTALATION) valve.

If that doesn't clean it up, you have excessive blow by caused by a worn out engine.
Refer to line 1 of this post.

 

I can clean the breather, but it was blowing enough out of it to get some on my charge piping. Not a ton, but defintly had a few drops on the charge piping between the the MAF and the TB.
