Hey guys. When I rev my car, it tends to blow black smoke. He is a video to assist you... sorry if it is not very good. Black smoke is oil related correct? I have an aftermarket exhaust, everything else is stock. Thanks guys. Any help would be appreciated.

Oil smoke is blue/purple colored, black is usually fuel related.

 

You have to give more info than that for people to help diagnose the problem. How many miles on the engine, turbos? Could be the turbos are burning some oil, could be crap burning off your pre-cat or cat. Take the intake off where your twins are and see if there is any oil on the turbo or in the intake system. Does it smoke ALL the time, or when you first start it up and rev it?

 

I get condensation when I start up... I don't rev it when its cold. The engine has about 30k mile on it. The exhaust and pre-cat are fairly old and not very good... could that be the cause?

 

i think its just crap burning off, you shoudnt worry

 

The only time I have seen black smoke from my FD is when the vacuum line popped off of the MAP sensor. It is now ziptied.

You may want to check that.

 

+1, Same thing happened to me.
