When reassembling the heater ducts under the engine is there a high temp sealing material that goes between the joins or is it just metal on metal?
Picture is just an example of the joints, but I'm asking about all of them.  |

In addition to the rectangular gasket shown in the picture in post #2, there's also a U-shaped gasket that goes in the branch piece shown in the first pic. It fits in the channel at the front of the branch piece (under where the clamp part gets attached).
Unfortunately, I haven't seen that gasket available anywhere, and each side is a slightly different size. I was going to cut up an extra set of the rectangular gaskets to fit, unless Mark comes out with the correct gaskets before I get around to installing my heater parts. |

I have never seen a gasket in that location and there is not much gap for one. I got the 1" x 1/16 rubber cork gasket material. It was $10 for a 100 ft roll. I am going to try a piece there.

IIRC, the gasket was silvery and didn't look like cork, like the rectangular gasket. It seemed like a metal or metal-mix, like lead and/or asbestos, and maybe 1mm thick. Or, maybe it was cork that picked up so much metal from the fan shroud that it looked like metal. Either way, it was very fragile and would break if removed.
That adhesive cork strip looks like it might work pretty well. |
