I was thinking about the cabin heat valve, and it's operation. I'm getting the stainless steel cabin side unit that is like the one from Van's, but this question applies to the firewall side unit as well.
If the valve is open to the full hot position, all the heat from the heat muff goes into the cabin. No problem.
If the valve is closed to the full cold position, all the heat from the heat muff goes overboard. Again, no problem.
If the valve is in an intermediate position, some of the heat from the heat muff goes into the cabin, but the potential problem that I see is that the valve is now halfway open to any gases, fumes, or fluids in the engine compartment. Is this a problem?
