when i'm driving I get a gas odor. not always . there's no leaks. what do think. Also i'm going to change exhaust gaskets from exhaust housing to engine pipes should I use copper gaskets?
the other question is what tipe of gaskets should i use from exhaust manifold to engine pipes ?Odor of raw gas or exhaust? If raw gas there must be a leak somewhere. Lift up the carpet in the trunk and check the connections on the top of the tank & the hose from the filler to the tank.
If an odor of exhaust, check for exhaust system leaks but a common source is a too short tail pipe. This lets exhaust gases exit into a low pressure area right behind the car. Check the trunk lid seals. A longer tail pipe & or a down turn at the end gets the exhaust out of the low pressure area.
Even with all the above in proper working order I have found that opening one window seems to encourage exhaust fumes to enter the cabin. The solution is to at least partially open the passenger side window.
By the way even when the top is down and driving at speed, i also seem to get gas odor, I'll look into the trunk suggestion.
When's the last time you checked all of your fuel lines? I had a very faint fuel smell, then it got real bad and I saw a drip from one of my braided fuel lines. Worth your while to check.when i'm driving I get a gas odor. not always . there's no leaks. what do think.
