Thread: Help with oil blowby

Guys i not sure what is going on. I changed The PCV valve and hose but i still am getting alot of blowby out of the tee on the valve cover. It looks like oil and water mixed. I checked the oil and it looks clean. Anyone have any ideas?

Do you still have the black box (Oil separator) on the front of the engine?

No dont have that it hasnt been on the car for over ten years. This problem just started here recently. BTW this is a Boosted car. And when i say alot i mean enough to make a puddle under the car after i drive.

Sounds like your rings are going, or you've got a blockage in the PCV system somewhere, or you've overfilled with oil maybe.

i think it might be the rings this car has been NOS'ed and turboed so for an under statement it has had the shit kicked out of it.

well then it prollly is the rings if its been through all that lol

Compression test and do a leakdown. Sounds like time for a rebuild!

Yes sir, i concur on ring/piston damage.

Aside from compression and leak down test do you have the hose thats tee'd off and goes into the intake just before the throttle body attached ? Its a dumb question but you would know right off the bat as it would prob blow the oil stick out under boost .almost everyone i know caps it off and puts one of those small breather filters on there . Again comp + leakdown first .

well did a compression test this morning it wasnt very good.
