Engine fumes in passenger compartment
I just bought a '92 SE, with 96K miles on it (I'm living in Israel btw).
After driving it for about a week, I realized that after each drive I have a burning throat, and start to feel a bit drowsy. At first I thought that it was the fact that the previous owner was a heavy smoker and used to smoke in this car all the time that caused this (I'm a non-smoker), but after cleaning and vacumming the entire car over and over again I realized it was not it.
Then I started looking at the ventilation system. Air is flowing freely from the intake ducts just under the windshield and into the cabin, like it should. The problem is that I can smell fumes from the engine bay (just the normal smell of a 10-year old running engine, nothing unusual) over those ducts, especially after the car has been driven for 10 minutes or so. I'm pretty certain that the problem is there - engine bay fumes entering the HVAC tunnels. I suspect that the rubber thing that'* supposed to seal those air intake ducts from the engine bay isn't doing its job properly (it does look a bit worn out).
Anyway, my question is: Has anyone experienced something similar? Do you think re-sealing this gap (between the hood/engine bay/ventilation air intake) with a some kind of rubber could be a permanent fix? Could it be something else? I'd appreciate any input.
Thanks in advance,
