Original Intake Manifold
 

Hello, my Intake Manifold is cracked. A vendor in the USA offers me a good original one. Is that a good idea or should I wait for a new one. The new manifolds are out of stock until summer. Thank you for your help. Many greetings from Germany. Gernot

Are you able to get the cracked intake apart from your current exhaust manifold? Sometimes they fuse together with age and it's very difficult to remove one without damaging the other. Worth looking at before you decide to buy a new intake by itself.

Thank you alexiskai. I don't know. I will try to take them apart.

As long as the new one doesn’t have cracks in it then go for it. That is assuming you can’t fix your other manifold.

Thank you Mike.

When you get your new one, bolt it up with the exhaust manifold and place a steel ruler across all of the flanges. Make sure that they are ALL on the same plane, or the setup needs to be ground/machined flat.

There are basically 3 different manifolds, one with our a vacuum hole (BOP-6/29), one with a high vacuum hole (7/29-7/30) and the last with a lower vacuum hole (7/30-EOP).

Also, be careful that the thickness of the mounting flange is correct. When an intake manifold is bolted to a exhaust manifold, they should be machined so that the mounting surface is flat across them.

Several good suppliers here in the USA, try another one?

I have a 1928, and it has zero vacuum pots.
