Tracing down the funky heater smell problem I see what a previous poster
meant about numerous places where oil can get inside these things (and hot
air can get out). I also see that they are lined internally with fiberglass
cloth, which presumably wicks up said offending oil. Some bright chap had
cut one of the boxes open, removed the glass, and welded it back together.
I'm thinking of doing the same with the other one, but reassembling it with
bolts and hi-temp silicone so that if it ever gets dirty again I can take it
apart and clean it . The boxes are in too good a shape and too expensive to
replace to just throw away. Has anyone ever done this? Are there many folks
on this list with the old aircooled vans?
