if you have a turbo you need to get a Catchcan system on there FAST.you are do alot of harm..the sound your hearing is the pressure pushing back thru the oil gallies so as the oil is flowing back to the pan there is to much pressure coming up..you need to have someone look at it fast before you blow out your oilpan gasket and valvecover gasket..im guessing if no pcv box its a b18b block GET SOME ventilation on that

My bet is that if you put the catch can on there you would either see steam or oil filling up and coming out of the catch can. Have you noticed either coming out of the valve cover relief that i think you mentioned in your first post?

Do you have an Oil Pressure gauge in the car? What does it read?

I see people out there spending money on the car to improve it … If you spend half that effort just working on your driving skills, making you and the car work together as a team, then you’ll go faster – period. To make the car go a second faster on the track takes a lot more energy and money than making yourself drive it one second faster.

to much heat in the piston will make the oil ring stick to the piston and not float freely which will allow for the smoke and there to still be compression across the engine.

also, like someone else stated..... check to see if your pcv system is working well

my lag is your courtesy head start


ATTENTION.... installing a head gasket, head studs or pistons and rods in your otherwise STOCK engine dose not make it a "built" engine! stop listing you cars for sale saying they are built when its not!!
