sr20 smoking.

[drunklowlife]

redtop sr20 (rwd) 6/20:Hot day (+90f) light white smoke (cigarette density) out muffler at idle. oil on #3 plug. pulled #3 injector to test and it started running real rough. #3 compression = ~160#4 compression = ~155.. #3 plug wasnt screwed in too tight (my error) so i got it in there good, and the smoking stopped.

6/29:Hot Day(+90f) smoke is worse at idle.

I do suspect bad turbo. coolant color/level looks pretty good. No leakdown has been done yet. any ideas? hopefully not blown h/g...

do your leakdown test. oil can sometimes be white smoke, although usually blue. your leakdown test will tell you if its coolant or not.
