about 1 month ago i notice there was somewhat blue smoke comming out of my muffler. I notice the smoke while i came to a stop, then somewhat it kinda went away but came back and now it smokes while i let the car park with engine on just idling, but when you drive the smoke kinda goes away but when it's under boost it smokes alot. I just recently did a compression test and the compression is #1 230psi/#2 225psi/#3 235psi/#4 230psi so it seems ok, also when I took the spark plugs out to do the compression test, they were all dry no oil. Could it be the valve stem seals? or what?

Motor still runs very strong, just smokes.

set-up is stock top/bottom end lsvtec
garrett t3t4 57 trim set-up.

Check Valve stem seals/guides? Compression and Leakdown won't help in that case.

Could also be turbo seals. Do you run a catch can?

seals, either from head or turbo.

how do u tell its the seals or guides?

kseriesdreams

had the same problem on my b16. assumed it was the turbo seals. had oil lightly leaking from the bottom of the turbo. randomly smoked for no reason

im gonna drop the down pipe to see if theres any oil in there cause theres absolutely no oil dripping from the turbo.

ok so i dropped the down pipe and found no oil in it, also no oil leak from turbo, the turbo was a brand new garrett now has about 2000-3000 miles max, so must be from the engine, how do i determine if its from the head or block?

Im thinking valve seals, because the block still gives out very good compression. what do u guys think??

jdmcivic2fast

anyone??

Did you ever figure out you problem? I'm going through a similar issue.
