Hi guys... I have an 04' S-Type 4.2 and I mostly do just local driving and don't really get the chance to "get on it" and open her up. Yesterday however, I did and I noticed that a puff of smoke came out of my exhaust when I looked in my rear view mirror. Is this due to the fact that I do so much local driving and it is just cleaning itself out or should I be worried that something is wrong? She runs fine and she did get up & go! Feed back Please!!

 

I wouldn't be concerned at all.

 

Hey Uptown,
A lot of time condensation will build up inside the mufflers and the piping of the exhaust and it will come out in a puff of smoke.. Nothing to worry about, but as a precaution you may way to check the level of your coolant and your oil, just to make positively sure that it's nothing more serious.. Eric

 

You need to replace the smoke osilation module for the center exhaust
