Noxious odor, Creeping into my cabin Options

[davidcalvin]

That is.. in my 914. It smells like a solvent or exhaust or something. Its not coming from the engine room er compartment. It not a cleaner or anything. Best I can tell is its coming up through the gap that the heater lever sticks out of.

If I run the fan, I get no smell. Obviously with the top off, I get no smell.

What could this be? I am guessing its exhaust leak from the underside leaking up into the cabin. The gf gets headaches when we ride (she has to have the top on).

Any guesses? Suggestions? Other than riding with the top of :-)

It's the rust on the heat exchangers that soaks up the oil and causes it to spread out over the surface of the heat exchangers. Stainless steel will cause the oil to run off the surface. They might still get a little oil on them, but that small amount will burn off them quickly when they heat up. You can have them surface treated a few ways, ceramic was mentioned, I think that's the same thing as the high temperature powder coating I've heard of. Rather pricey. I'm going to do mine soon. I plan on getting them dipped, then painting them with a high temperature exhaust paint. You then need to cure the paint, by running the engine to heat it up, then shut it off, let it cool down, and repeat a couple of times. See the Platings, Heat, and Cost thread.
