Okay, so I have been boosting 7 lbs of boost on my 99 Si. I know I am getting blowby because I did the test where you hold your hand over the breather to see if it makes the psssshhhh noise and it did. My question though is, what are all the factors that could be causing this?? I am guessing the ring lands, but I am not sure because the motor has not been tore down yet. If you could list some other things it could possibly be I would greatly apperciate it.

 

yea

 

your shop should know the answer to that question
