i have a hatch with a ls motor and i just put a turbo kit on about 2 months ago. Last night after i got in it a few times and when i parked white smoke was just pouring out the exhaust. But when i was drivin home normally there was no smoke at all. Its happened a few time before but it doesnt do it unless i get into it a lot. I also have a leak from the rear main seal but i doubt that would be why smoke is coming out the exhaust. I know im burnin oil too becuase its on the back of my rear bumper. Sometimes after i get into it but not often there will be a blue tint to the white smoke but its not a lot. But last night it was all white and just pouring out the exhaust. Could this be piston rings or maybe headgasket?

 

Most likely your head gasket. Check if you are running low on coolant and check if your oil has some water in it.

 

what kind of oil are you using? if its 5w20 its too thin and is seeping past your seals so try 10w30 because it is a little thicker and let me know if it still smokes

 

White = coolant

Blue = oil

Chances you are either blowing out the gasket/lifting the head when you're putting load on the motor

 

Herman I told you that motor didn't look healthy when we first tuned it. Its been smoking ever since then. I know it was at least when you were racing those cars just a couple of days later. Like i said i would do a rebuild. Looked like all oil to me.
