Breather filters are garbage and should not be aloud to sell on the market!!! The only true way to fix your problem and still have the PCV system functioning correctly is to get a catch can. As soon as people dont run the breather line back into their intake like its suppose to your going to create more pressure in the crankcase. The DC3 catch can is what i run in my car, I would reccomend that over most of the others on the market.

 

Wow. that was cool. i think i might have to do that. doesnt look like it will hurt the effeciency any either.

 

catch can, u proably have a lot of oil in your turbo inlet pipe to.

 

Yup I have a heavy foot, so lots of blow by oil, I guess. Oil is making my maf sensor act up too. Maybe a simple fuel filter may not work. Anyone have a picture of their catch can installed, maybe a greddy or cusco?
thanks

 

The vaccum nozzle(for your breather line) on your intake is past your MAF sensor so i'm sure your MAf is fine. Its probably just build up over time in your IC pipes, regular 2.0's dont have that much blow by...unless your rings are shot. Just get the DC3 catch can. $150 shipped
