smelling exhaust when i turn on the heat??

jaehow23 · November 11th, 2011, 03:26 PM

now i know this can't be normal...right? It doesn't matter if its just the heat or if it's the defroster, I turn it on and I smell like my tailpipes are re-routed through my windows 0_o any suggestions? what should I be looking for?

Well I'm pretty sure the defrost pulls from outside air. Do you have any exhaust leaks?

jaehow23 · November 11th, 2011, 03:34 PM

^^^ I'm not too sure, is there a way to tell? The guy i bought it from put an o/r H on there and that's about it...but i'm not sure how to tell if there's a leak

Does it do it even when you're driving down the road?

Sounds for sure like you have an exhaust leak that is getting into the interior.
Maybe a leak around your H-pipe or something.

yes, when i'm driving and even more when i'm not in motion. should i take it to a shop and have it looked at for a leak?

I am going to say you have an exhaust leak.

Probably leaking at the driver' side manifold-H pipe connection.

do you have any "tick" sounds ?

I agree with exhaust leak but my impression is heat/defrost come from the engine bay area drawing ambient heat. MAY BE WRONG!!. but id start for checking for leaks from the headers/manifolds then follow exhaust out back. even when my car ran rich with no leaks leaks my heater didnt smell like exhaust.
