So far I've replaced the gaskets on the exhaust (head pipe and muffler, the muffler needs to be replaced as I can see a very small leak in one of the seams), installed new door seals that had been removed by the previous owner. Also found he wasn't very careful when installing the rear tunnel cover in the backseat. It only had a couple of screws that were too short and only went into the carpet. And since I don't drive it in the winter I have also sealed (can you say duct tape?) the air returns on both sides above the axles under the car. All of this has helped but.... still there, more noticeable at highway speeds than around town.
The engine has about 2500 miles on an overhaul so it's not like there's a trail of smoke or anything, more like I'm piping exhaust inside.
When I was rebuilding the accelerator linkage I noticed that the tunnel has a couple of large cutouts from the factory on the side and top near the front. The rear of the tunnel under the car is wide open. Is this suppose to be sealed somewhere between the front and rear to keep fumes out?
Anybody else had this problem? Any thoughts would certainly be appreciated.
