RivNut Posted November 10, 2021 Share Posted November 10, 2021 that goes between the passenger’s side exhaust manifold outlet and the heat riser for your nailhead? It’s a simple flat exhaust gasket. Someplace local so I can do a trial fit. Link to comment Share on other sites More sharing options...

telriv Posted November 10, 2021 Share Posted November 10, 2021 Take the heat riser with you to NAPA or an exhaust shop & they should be able to fix you up. IF I remember correctly the size is for a MOPAR. Shouldn't cost more than a couple bucks. Tom T. 1 1 Link to comment Share on other sites More sharing options...
RivNut Posted November 11, 2021 Author Share Posted November 11, 2021 Going to have to find a new NAPA. I called this afternoon to see if I could look and compare gaskets to my heat riser. The counter person said, "There all in boxes. Open a box and consider it sold." There are some more options to explore so I'm not giving up hope. IF I do find a good one, I'll be sure to post a brand and part #. Link to comment Share on other sites More sharing options...
EmTee Posted November 11, 2021 Share Posted November 11, 2021 Will NAPA sell you a sheet of the gasket material so that you can make your own...? 1 Link to comment Share on other sites More sharing options...

1965rivgs Posted November 11, 2021 Share Posted November 11, 2021 (edited) Ed, The Napa in my town has gasket boards for each type of gasket with the size and outlines of the gaskets. You need exhaust Napa gasket # 31534 which is a perfect fit. Tom Edited November 11, 2021 by 1965rivgs (see edit history) 1 Link to comment Share on other sites More sharing options...

RivNut Posted November 11, 2021 Author Share Posted November 11, 2021 (edited) I found the gasket. 😁 Part #31534 is good at NAPA, Advance Auto, AutoZone, and O'Reilly's. (the only four that I Googled) From what I can tell it's a universal gasket. No name on the package but O'Reilly's shows it as a Nickson, Advance and Autozone show it as a Walker, NAPA shows it under their NAPA Line. The package just says "Exhaust System accessory" Made in India. If you're redoing your system, here are the parts that I used: Makes one stop shopping easy. Gasket between manifold and heat riser - 31534 Short studs - Dorman 675-082 Long studs - Dorman 675 - 109 These studs are 1/2-13 where they go into the manifold, and 1/2- 20 for the nut Grade 8 nuts - Dorman 962-023D (1/2-20) Grade 8 split lock washers Dorman 965-114D (1/2" ID) I got all of these parts at O'Reilly's because it's closest to me. These #s are good for manifolds with the separate heat riser. I would imagine that if you have the built in heat riser, you would need four of the shorter studs, and none of the longer ones and no gasket.

telriv Posted November 11, 2021 Share Posted November 11, 2021 See, told you they were readily available. AND, IF you go a little further you will find they are a shim steel gasket originally for a MOPAR. Tom T. Link to comment Share on other sites More sharing options...
RivNut Posted November 11, 2021 Author Share Posted November 11, 2021 When I was looking for the part at different jobbers, a lot of applications showed up. Most common was where an exhaust pie connected to a catalytic converter on newer cars built in Asia - Kia, Hyundai, etc. Link to comment Share on other sites More sharing options...
telriv Posted November 11, 2021 Share Posted November 11, 2021 That may be true Ed but I'm using my memory from years ago. Tom T. Link to comment Share on other sites More sharing options...
RivNut Posted November 11, 2021 Author Share Posted November 11, 2021 I understand. I was not doubting you, I was just relating info that the gasket in question is still being produced for newer cars so there should always be a plentiful supply.

Chasander Posted November 12, 2021 Share Posted November 12, 2021 (edited) Ed Is the lock washer shown in the parts manual? The lock washer could lose tension and the nut loosen due to high heat. Aircraft grade nuts are very hard preventing a lock washer from digging in. Edited November 12, 2021 by Chasander (see edit history) Link to comment Share on other sites More sharing options...
telriv Posted November 12, 2021 Share Posted November 12, 2021 NO lock washers should be used on the exhaust flange nuts. Why try & over think what the factory did??? IF you want to do something positive use brass nuts. Tom T. Link to comment Share on other sites More sharing options...

Yes - you'll thank yourself in the future when you need to drop the exhaust pipes for some engine, suspension, or exhaust work! Link to comment Share on other sites More sharing options...
