When I turn on my SR20 turbo motor in the morning, I get some white smoke out the exhaust. I account that to the dew/humidity (yay Florida) and the fact that the car needs to warm up. While going through the normal RPM range, no white smoke is to be seen. However, if I idle for more than 30 seconds, it seems that I start to get a constant (but not large amount) stream of white smoke until I start going through the RPM range again. I've checked my oil (white smoke though, so I doubt that's the problem), coolant/water levels and everything seems to be fine. Only other smoke I get is at WOT, where I get a bit of black smoke (but I account that to running a little rich and burning some fuel).
I've heard a few things from blown head gasket to dying turbo. Car seems to run just fine though at the moment. Can't see any oil or anything in my water or vice versa. I'll be buying a compression tester this weekend to test that out. It was also suggested that I take it out on the highway for 15 mins...come back and let it idle and see if it produces the same results.
Any other thoughts/suggestions?
