Today my car started to have excessive whitish blue smoke out the exhaust at cruising speed while being in gear, but when i get on it it goes away then returns at cruising speed while in gear. I no it sounds like a head gasket or another gasket, but my engine only has 70k. I checked my oil and its clean and my coolant is straight. Does anyone no what else it could be????????????????????

 

r u boosted?

piston rings and valve seals come to mind

but if ur turbo most likely u have a bad turbo seal check to see if there is any shaft play

 

yea im boosted I got a greddy t3/t4 turbo running 6psi

 

yup, check ur turbo shaft play?

sound like its blown... how old is it? if its newer or brand new, go do a leak down and a compression test but i doubt you would have any internal engine damage at 6psi, unless u have a bad tune.

 

My turbo is about 2 years or so old. The smoke will start after driving my car for about 10 minutes and is present at cruising speed while in gear and a little bit at idle.
You said it might be shaft play in the turbo. Should thier be zero play or is minor play acceptable, because i took my filter off to see if thier was any play and if i nudge the shaft back and forth a few times with light force it slightly moves. Is that normal?????
Another question that i have is what steps can i use to determine if the problem is a head gasket or a turbo related problem such as a turbo seal or shaft play????

Like said above do the leak down and compression test.
