I have a 71 Hemi Cuda recreation and have a problem I can't figure out. . . .I'm getting exhaust smells in the passenger compartment when I hit the gas. I've had all the exhaust checked out and there are no leaks.

Is this maybe not exhaust but instead, fumes coming from the breather cap or something like that???

Can't figure this out and it's nasty every time I get on it. Can anybody give me some advice please?

Thanks.

Hows the trunk seals, body plugs, etc? Where does the exhaust exit?

you might put the rear up on stands open the hood put it in gear & get on it & see if you see anything. the car wont be moving but the source may be obvious enough for you to see it.

Had the same problem when I had a fiberglass trunk - poor seal.

Gasses were worse with the windows down. Since it was a Street/Strip car. I already had the speaker holes blocked and a firewall behind the back seat. Finally, I made cardboard covers to fit between the 1/4 panel and the wheel housings inside the trunk to keep fumes from coming forward into the car. I could not believe how much a little cardboard and duct tape helped!

You were right on the money. I put some Dynomat behind the seat a couple of days, finally, and it took care of the problem.

Thanks!
