i remember finding a website on the internet that makes this 1/2" thick gasket material for the intake manifold. It supposedly insulated all the heat from the engine block to the intake manifold. I have done many searches, but i cannot find any website that just sells sheets of it, so i can make my own gasket out of it. Does anybody knows where i can purchase this stuff?

thanks in advanced

Look up Phenolic gaskets I have a feeling that is what your after.

I found pretty nice sounding gasket material on mcmaster.com part # 95715K63 ... maybe you can try that out.

They also have them with steel wire inserts that someone on the foums here had used as exhaust gaskets with good results... part # 95675K67

BTW, in my case, a 1/2" gasket resulted in clearance problems, BUT I think it does keep the intake cool.

has anyone had any experience with teflon? you can buy a 12"x12"x1/8" sheet for $25.

I was going to use v-band clamps, but i decided that it would make for a more efficient setup to not have a hot intake manifold.

I made a set for my FD out of hard phenolic 1/4" or 3/8" from McMaster. They work great--been on the car for over a year with no problems. (approx. 7,000 miles) I used these for engine to LIM, LIM to UIM, and UIM to TB. It definitely slows heat transfer and help keeps things a lot cooler in the engine bay.

One thing to remember when doing this is that you need to extend the length of any bolts and studs by about the same thickness as you add. I also used a stock gasket on each side of the insulators and have had no sealing problems.

Yes, I made all my intake gaskets out of the stuff -- TB to UIM, UIM to LIM, and LIM to engine. I think it's the ideal material. It has high heat resistance, doesn't stick to stuff with time and temperature, is easily cut with a razor knife, and seals well.

Cool. Did you use the teflon as a gasket or did you add gaskets between the teflon and manifold?

BTW nice spacers Speed of light, I wish I had a mill!

Thanks. You actually don't need a mill to make the phenolic spacers--a scroll saw--such as you can get at Sears is excellent for working with this material (and much more forgiving than using a mill).
