Brz Blowing Smoke
 

Hey guys, so a buddy of mine has a 2019 brz with approximately 20k miles on it it has a full cat-less exhaust and is tuned using oft stage 2 (93 octane). He’s the first owner bought it off the lot. and right at about 17k i had noticed his car was blowing a little bit of white smoke (sometimes blue tint to it) and we had blown it off just as condensation but now at around 20k it has gotten a lot worse, Clouds of white smoke on startups both cold and hot and blue smoke sometimes while driving. We had preformed a head gasket test and it seemed fine and he’s been checking up on all his fluids and it doesn’t even seem like it’s burning anything… i’ll include a link to a video of the startup here vvvv

I’m pretty lost as to what it is, you would assume head gasket issues but the oil and coolant aren’t mixing and no fluids are being lost but it’s pretty smokey?:bonk:

Blue Smoke = burning oil
Thick White Smoke = burning coolant
Some white smoke = vapor
Black smoke = too much fuel

yea i know the typical white cloudy is coolant and blue is oil but his fluid levels have stayed the same for the past few months and it’s still pouring out smoke

Check the replies on the posted thread link. Steve99 has some good answers when it comes to tuning and problems related to it.

Quick and easy thing to do is log the car with OFT and upload it to datazap.me and post the link here. Follow the logging steps in the link in the signature line of user steve99 in the link spcmafia posted. No guarantees' but we may see something there. Log the following:

Is he measuring coolant through the fill neck or only using the reservoir?

Maybe pull the pvc hose off the intake. See if there is excessive oil in the hose. Same for the valve cover vents.
