i have been having problems with my car smoking a little out the exhaust after a hard boost. it doesnt billow out the back or anyhting while boosting but after i come to a stop is when it smokes a little bit as to where i can see it in my rear view. i have no oil in my downpipe or in any charge pipes and the coolant level is perfectly normal with no overheating. the color of the smoke is greyish. i just cant figure this out. i will try to take a pic of my oil return to see if that may be the problem. i need any help

try doing a leakdown on the motor. what year is the head and have you given any thought to valve seals??

tyflip2

i was thinking valve seals but how do i check to see if it may be those. i only see the smoke when i come to a stop, it doesnt really come out when im accelerating. how do i check the seals

spark plugs.

sounds like valves seals to me.

tyflip2

are they hard to change and what is involved?

you'll burn oil, it will continue to smoke and your car will smell

hey....you've got exactly the same problem i do!! and yes it's my valve seals as well!! i just got done checking compression in my built ls and compression reads as follows:

1 = 185
2 = 185
3 = 190
4 = 190

everything looked great and dandy but when i stuck an extension into the spark plug hole onto the piston, i brought up a little bit of oil in cylinders 4/3/2. which i'm sure is due to the valve seals. my car burns oil like there's no tomorrow but i'm not worried as i have another head that i'm working on that will be mildly built with new seals etc.
