Got Heater S-tube gaskets'? Options

[JeffBowlsby]

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.

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
