I have read many posts on exhaust fumes in the cabin and have done a lot of the recommended remedies but I cannot seem to get it to go away. I have done the following:
- replaced rear hatch gasket
- replaced firewall gasket
- replaced sunroof gasket
- replaced inner and outer gearshift boots.

The smell isn't constant but I always smell it at some point when I drive the car (daily). I haven't been able to correlate the smell to any set of circumstances. Its definitely not coming in through the fresh air vent.

Any suggestions?

Have you checked the battery box to see if it's rotted and letting fumes into the cabin from the engine compartment? Also the firewall rubber grommets and seals.

I have checked the batter box it was fine. I will look closer at the firewall grommets

close the windows.

Mine lets fumes in through the shifter even with both boots. The foam surround inside the tunnel is rotted away on mine. Could be that?

Check to make sure the tail lights are sealed properly

It was a little ragged what did you do to fix it?

I haven't fixed it yet. The roof is off 95% of the time anyways. But I'm not sure if anyone sells them new. I think the best bet might be to try used? Someone might have the foam surround still in good shape. They tend to fall apart pretty easily and make a mess.

What year is your 944? If you have a late 944 with tubular headers, they could be cracked and you would smell the fumes in the cabin (or at least I did with mine). I was also be able to smell the fumes under the hood on the exhaust side of the engine while idling at certain times.

Tailights, or the cubby plugs or spare tire plug is missing.

On my 92 I had a problem with a cracked barb at the tank, the one for the return line. This leaked gas which pulled back there and also rotted the end of the return line. Easy to spot with the trunk carpet up and the cover off the fuel level sending unit access port (under some sticky matting.) Not too hard to fix either, JB weld and a new section of hose chased down after the old return line via a strong line.

I am not sure what year car you have but maybe a late 944NA as per the wheels and bumper so yours should be more or less the same.

it is an 87. see photo, i am assuming the headers are cast... i have only had the car 3 months so who knows what has been done over the years. yesterday going home from work it about ran me out, clothes reaked of exhaust, this morning coming in, i smelled it for about 5 mins, last 15 minutes I didnt smell it. this is driving me insane.

. I looked at that this weekend and all was good, sealed around the cover too, the smell is not so much a gas smell, but exhaust. my clothes smelled leike lighter fluid. if you smell the output of the exhaust pipe, it isnt bad at all. very bizarre..
