what could cause excessive oil blowby on a sr20 if it has a new pvc valve? could it be the rings?

 

anyone have any ideas? its just that it blows that oil and then some drips burns on the turbo mani thats it so im scared to take it to high rpm's any leads?

 

how much boost are u pushing?

 

it is running 10 psi on a t3t04 turbo here is a mod list
-apexi headgasket
-stage 2 cams
-t3/t04b turbo
-fmic
-oil catch can w/ breather filter
-braided pcv vacuum hoses
-greddy type s bov
-act drag/strip clutch
-greddy downpipe
-gutted cat
-apexi ws exhaust system
-walbro fuel pump
-z32 fuel filter
-bkr7es11 ngk plugs
-new oil change
-new pcv valve

 

it may just be the fact that u got a new PCV valve and it was clogged before and now its flowing freely....cuz i have an oil catch can on my non boosted engine and it barly ever has to get emptied.....i think its just boosted engines that get all that shit but like i said it may be the fact that u got a new one and the other one was clogged bad or somthin....if thats not it then it sounds like rings....but dont jump to conclutions yet....thats all i can think of tho......

Try a leakdown test.

 

Where is the oil dripping from? When you say that it drips on to the manifold, it makes me think that you've got a breather on the valve cover. Your description says that you have a catch can though. Tell us how you have the valve cover vents, "black can" factory strainer, and crankcase vent.

 

catch cans dont work unless it's sucked out by a vacuum source. you cant let it just vent out on its own.
