I have a 70mm RPM Services TB on a Blox Intake manifold for a B-Series, and I need to know which gasket to use and where to get it if it's not an OEM part. Any help is appreciated!

 

I would like to know myself. Should I just make one?

 

silcone gasket maker

 

i used a stock one, and with a razor knife, cut it so that gasket would not get in the
way of air flow.

 

Autozone sells raw gasket paper composite, just trace out what you need and cut it with an xacto knife. The piece is usually big enough to make 3 or 4 gaskets. It comes in different thickness's.

 

I took a piece of 1/8" thick cardboard-type material traced a stock gasket on a cad program and used a laser cutter to cut out a custom gasket with the bore enlarged to the proper size.

Of course, that was complete and utter overkill - and really, all it really did was make it a pain in the *** to adjust the throttle cable. Oh, that, and make me feel cool for using that really expensive machine?

I'm pretty sure a stock B16 gasket + xacto knife would work out nicely. ;o)

i'm sure rpm sells the gasket. my edelbrock tb came with the gasket.

 

does rpm service have a website of any kind? I searched google but found nothing

 

rpm service does not provide a gasket for their t.b.
they recommend using a thin layer of rtv silicone gasket maker or cutting one out of paper gasket material as tbone suggested.

cool thanks guys.

 

I guess you guys all issed where I said to make your own for approx 6.00 from Autozone..lol

Silicone is a bad idea. If you havent done it before and you apply to much it will squeeze out when you tighten the tbody , then it hardens and and the small hardened piece falls off and makes it way into your intake and your IAC valve. Then the iac gets stuck and your wondering why your car idles like crap. Then another piece goes into the intake port down the runners and ito the cyl, at this point is goes either out if your lucky or down into your ring gap , clogs the ring and you lose cyl pressure..
You guys can laugh but i have fixed this exact problem 5 times in the last 12 years in different variations.
