- Buick Ownership
I have a 1968 Buick Electra with a fairly new exhaust system. After 20 minutes of driving the inside of the car as well as my hair and clothing smells of exhaust smoke. I also get a bit of a headache. I’ve taken the car to several mechanics and they can’t find any major exhaust leaks. There is a pinhole leak in the lower manifold where a heat riser for the choke is located, but they all seem to agree that wouldn’t cause the smell inside the car. The belief seems to be the car is running too rich. Perhaps? But wouldn’t I smell it outside the car rather than inside the car? What’s going on and is this dangerous to drive?
