Exhaust fumes killing me...

Trickflow.GT · May 16, 2008

Yea, so when i sit at a light and have the heat on, my car fills with exhaust smell....so much so that its unbearable.

Doesnt happen when driving only when idling.

:dunno:

Help?

exhaust leak around the headers or collectors? have you messed with you exhaust recently?

maybe EGR vlv on back of head

i only mention headers because about a month after i installed my shorties, i got the same thing with exhaust coming through, it didnt happen while driving because it was forced out and under the car. My problem was a head of a bolt snapped off on the header and was causing a leak around the manifold. it wasnt over torqued either, just a bad bolt. but I had to take the whole header off to get the rest of the bolt out of the head, which came out easily with my fingers. also check around the collector, i have know of a few collector studs randomly breaking. just a though.
