As much of you are correct, Im suprised only one of you mention checking compression and leak down...

If you see a increase of crank case pressure its mostly cause of piston ring failure.

Double check before you bandaid a real problem.

Good Luck

Can u post a pic

 

If it was as bad as that, then wouldn't you be blowing blue exhaust fumes?

 

Are you venting the front valve to the atmosphere or running it back to your intake pipe?

 

Not always, some times. Just depends how its leaking, where when how.

 

make sure your pcv valve is working and also doing a compression test wouldnt hurt just to be safe.

 

when your running big boost you going to pressurise the crank case more than if you was on std boost. the more mileage you have will effect this more too as your leak down percentages increase with normal wear.
more venting is good
a spring is good (for saving messy bays)
resolve your blowby issue if its excessive.

evoryder have you any pics of the map vents installed?

 

WHen I get my hands on a digi cam. Maybe tomorrow. It's pretty straight forward.

Recirc back to intake. I have a catch can on the intake side, will be adding/upgrading to the saikomichi oil catch for pcv and intake side

 

 

thnks. So I still need a breather system though.

BTW WTF is that Air filter

 

Perrin Filter...one of the top flowing filters you can buy for the evo.

 

Good info!
