Anyone else have these gaskets (the two at the bottom)? They were glued into the edge channel on the S-tube hot air ducts where the clamp onto the fan housing...I have not seen these before.
Has anyone bought these new? Got PN's? I don't see them in PET. Attached image(s)

Hi Jeff, A few years back I bought the new ones, When I put them on and intalled the heater branch pieces I realized they were a pure waste of money. The fit was very loose and would certainly allow leaks of both air and oil and when raining water (quick steamup of cabin) I redid the entire system and this time I used the High Temp Red silicone sealer. I cleaned every surface that needed sealing and applied a generous amount in all the places the gaskets are supposed to be. I let it set up fully (it remains flexible and compresses well when the clamps are tightened). Just yesterday I had to remove the engine in my daily driver to locate and repair some front of engine oil leaks. When I removed the branch pieces from the heat exchangers there was an abundance of oil all over the joints of the branch pieces and the heat exchangers, but not even the slightest trace of oil made it past the silicone sealer...the heat exchangers, the branch pieces, the warm air guides, and the j-pipes were oil free inside................In case you just have to have the original cork type seals, AA can fix you up for about $60.00...................They are listed in the PET as gaskets for lid....part numbers 021 256 325 A (right) and 021 256 326 (left)....................Jerry

I made the narrow one from a valve cover cork gasket, just cut it down and glued it to the Heater box. Worked great. I was not aware of the other gasket. Should be easy to make from gasket blank sheet.

for cheapo gaskets make a VERY slight bead of black RTV on what would be the mating surfaces of the clamping pieces and the inside edge of the branch ducting where the meet the heat exchangers. allow it to fully setup prior to install. one vendor used to list them in their catalog. quite expensive for what you get.

Thanks for the replies. I guess no one has the two lower gaskets in the photo, per my original question. Pretty sure they came glued into the metal duct piece new, these are a harder denser material, off-white in color, than the cover gasket (which is black and more resilient) that can be obtained (top gasket in photo)

I used an o-ring. Worked OK but I suspect the RTV works better.

Based on advice from Brad Mayeur, I've used the red high temp RTV on a few projects with good results.

I run without any gaskets. Is there some real danger doing this?
