White smoke from exhaust
Hey everybody,
People who have driving behind me have being saying that there is white smoke coming from the back of my car.. does that mean the turbos are going? Currently I have a jb4, full turboback exhaust, intake for mods. Running e85 and 93 mix. |

I don't think we have enough info to say for sure. have you been consuming oil? is your car reaching boost targets on your tune? is the WGDC edging higher? all of these could point to turbos on the outs. Mine are failing slowly and I have some bluish-white smoke at cold startup as well as a burning oil smell through the vents when I turn or come to a stop.

Well I took a trip from Miami to Orlando and I had to throw in a quart after I had just changed the oil about two weeks ago. As for boost I dont think so I'm only hitting 14psi but I think that has to do with my low wastegate idle position to get rid of the rattle.

White smoke is normally water or coolant. In older cars that could be the sign of a blown head gasket or a cracked cylinder head. How is your coolant level?

Coolant has a VERY distinct smell, a syrupy sweet odor to it. Oil will generally smell like…well oil. That and combustion. It could be turbo seals; it could be a few other things. My seals are on the way out; car smokes a good amount…But still builds boost perfectly, no issues with high WGDC, WG rattle, etc. A lot of oil consumption with 5w-30, since switching to Motul 5W-40 it has dissipated a good deal. Car smokes the most when the motor is cold and is coming to a stop (under vacuum). However the actual cold start doesn’t really smoke much at all, 99% of the smoke shows up when coming to a stop.

Yup. Im pretty confident its turbo seals, but i wont know for sure until I get it on a lift. Very frustrating since they boost perfectly, dont rattle, etc. The smoking and oil loss is no good though.

I recently topped up 0.5L because it was nearing low and I had to add in another 0.5L after only another 1000kms... |

Used to have this problem, but it turned out to be because I was running cobb stage 2+ aggressive with the BMS downpipe fix turned up. My mechanic turned it down to zero since I passed the emissions testing, and the problem was solved.
