i havent had a whole lotta luck posting in here about this, but ill post to give this a bump:
causes: cold, and more cold. Originally mine did it all the time, after a trip to the dealer it now only does it when the motor's cold. After a 30 min trip to or from work, it doesnt produce the smell anymore. The dealer tightened a PCV hose i pointed out was leaking. The pcv hose was attached to the intake in the front of the motor.
heres some pics:
The yellow circle was the pcv hose that was leaking on mine.
My build date was also 03/01
My only mod is a cat-back exhaust.
The smell is still there after a trip to the dealer, I'm waiting for others on the midwest board to take thiers to a dealer and see if somone else can find the problem.
