I gave my car a good run tonight, I was high up in the revs in 2nd, 3rd and 4th on full boost (14psi, Mines ecu, twin mushroom filters, decat exhaust) and must of been at it for about 6 miles.

 

Once I stopped and was parking the car up I noticed whisps of smoke from the exhaust my wing mirror, whilst the car was cooling down I checked for smoke at the back but it had now stopped.

 

After about 5 mins of idling I notices a small amount of smoke coming from underneath the car, it was the drivers side directly below the wing mirror.

 

I decided to switch the car off. An hour later I started it and drove home, no smoke, and all seems fine.

 

Any ideas where the smoke is coming from guys?

 

cheers, Dan

Could be the rocker/cam cover seal leaking and dripping on to the exhaust, or maybe the oil feed to the turbo doing the same, just a thought mate...

As above or main seal.

i had similar before,

 

sounds like a leak, either oil, or air/exhast fume
