When I decelerate from a high speed, with the engine in gear, I get a strong smell of exhaust in the car. It smells like the blow-by from the crankcase ventilation system. I have already replaced the PCV valve, that had no effect. Any ideas?

RE: Exhaust smell

I hav had 3 z cars the problem is probably the exaust/intake manifold. Usually the bolt closest to the
firewall breaks off due to heat/rust. you will need to
take off. machine shop will true the manifold. replace
new gasget and bolt of course. reassemble, and your
exhaust smell should be fixed.

<b>RE: Exhaust smell</b>

mine went beyond that.....check the inner shift boot and if you put in a new one make sure it is sealed with weatherstrip adhesive or similar.....also i had to put in new taillight gaskets and inner hatch seal....now the smell is MUCH less and none if the windows are up.

Hey man, check around the tail lights, inside the cargo bay, for missing seals, also try extending your tail pipe out beyound your bumpers.
