heat riser gasket?
I have air coming out from around where the passenger side exhaust manifold connects to the heat riser. Especially when I give it some gas to accelerate. Is there a gasket there that I can replace. I was looking in the LMC catalog and only see manifold gaskets and the heat riser. Is there a smaller gasket that goes there or is it normal for air to come out of that area?

Re: heat riser gasket?
There's a donut gasket that is made to go inside there. Take the heat riser in with you to your parts store. The donut will go towards the engine while the flanged end will go into the heat riser.

Thanks a million. That will be the next weekend project.

Re: heat riser gasket?
No problem man. Just take your heat riser so that you can make sure that it's the right one. Once you pull the heat riser you'll notice a small ring around the inside of it which is the stopping point for the donut's flange so that it sits flush with the edge of the heat riser even before you apply torque. I bought mine at AAP and it took about 5 minutes to get it right.

Re: heat riser gasket?
I replaced the flange gasket today. It was the one at the bottom of the heat riser where it meets the exhaust pipe. The one that was in there was pretty bad and it was made out of some type of material that broke in pieces as I pulled it out. I replaced it with a metal flange gasket I purchased at ABC auto. Even though it is much better, I seem to still have a little air coming out the top part of the heat riser where it meets the exhaust manifold. I am wondering if I just need to tighten up the nuts some more to pull the heat riser in tighter to where it meets the exhaust manifold. Any suggestions?

Re: heat riser gasket?
You might just have to tighten it up in that manner. How is the gasket on that side?

Re: heat riser gasket?
LOL. I didn't know there was one on that side too. Im kinda new to this. I even asked the guy at ABC if there was any other gaskets for it and he said that was it. He said I could take the heat riser off and leave it off because the flap sometimes tend to get stuck. Do you know anything about that? What exactly does it do?

Re: heat riser gasket?
All that the heat riser does is build up heat in the engine when it's cold outside. It speeds the process up so that the engine works more efficiently and so that you can get on the road faster. Helps with the idle basically. And it should be a regular cork/steel 3 hole gasket. Can you get a picture of the heat riser on the exhaust setup underneath?

Re: heat riser gasket?
This is what I got today. Mine is made of sintered metal though. http://www.autopartswarehouse.com/se...3028+9870+5792
Is this the one your talking about. http://www.autopartswarehouse.com/se...3028+9870+5977 The one I got is sandwiched between the exhaust pipe and the bottom of the heat riser. I guess I need the top one as well? The one with the three holes.

Re: heat riser gasket?
Yeah you're pretty well off doing both. I'm trying to find a picture of the gasket that I had to get for my heat riser.
