White Smoke from Exhaust
Hey Guys,
I just installed my VRSF downpipes yesterday, and i am noticing puffs of white smoke coming out from my exhaust. It is most definitely not condensation, as the smoke lingers in my garage. When installing my downpipes, i noticed that my rear downpipe O2 sensor was covered in white powder, and so were the inside of the rear downpipe. With the downpipes on, i never noticed any smoke from the rear of my car, but now that it is completely catless, the smoke comes out in thick puffs! I did some research here, and thought it might be a coolant leak. I just checked my coolant level, and although it is not at min, it is far from max. Can anyone here advice what i should do? Currently the car only has BMS JB4 Stage 3 tune + DCI Intakes + VRSF Downpipes. The car drives great, and never has there been a rough idle or anything along those lines. BTW car has an N54 engine (sold the one in my signature). Help! Thanks! |

Seems like everyone is running into the same thing. I installed mine and saw small amounts of white smoke and smelled burnt oil. It looks like turbo seals to me as well... but who knows.

Really everything about it makes it a great tune. Better boost control, control of ignition, and more fueling. Everything a growing N54 needs to make good safe power |

I wondered why the new board wasn't just called JB5. Makes sense now.

I recently had white smoke issue and coolant was low every few months....... I had a bad oil filter housing gasket, dealer said coolant pressure kept dropping due to above. I was hoping for new turbos but they're still running strong.
Everything on my car that could be fixed has but the turbos and hpfp....... 66k so far, they even fixed a leaky muffler bearing and they used a metric crescent wrench to fix it. Check ur coolant pressure
