so the other day i noticed smoke coming from my tail pipe, cant tell if its blue or white. i thought it was a headgasket, till i did compression test and leak down. leak down was at 15% and compression was 145 straight across. no bubbles in radiator or coolant resevoir, and no milky oil dipstick. so i pulled my down pipe and saw a puddle of what seems to be coolant or oil, cant tell since its all black. i did pull the intercooler and saw no oil inside as well. is it possible the turbo is leaking only on the exhaust side? ill post a pic to be more clear. any help?

my guess is turbo seal starting to go?

car still holds boost fine and i see no loss in power. ill try and post a video of car smoking as well

I'm actually on the same boat. White smokes blowing out but no visible signs of leak/power lost/head gasket/oil/etc. (Smell like..... Smells like an exhaust)
Only note is that my heater core is plugged/bypassed (By Previous owner) because I have no heat with the heater on (Car is not overheating) - Just did the timing service so everything was flushed/burped. (Thermostat is not stuck opened either)

My possible conclusion was that it was just condensation (It's getting colder) or a very minimal leak somewhere not seen. But I ain't no mechanic so don't take my word for it.

If anyone else has some input on this, I'd like to know as I'm intrigued to learn more.

i also did the block tester to check for headgasket leaks, and it passed. liquid stayed blue with no hint of yellow.
