Thanks, Sheldon. Tell Leonard and Penny HI.

If you have secrets, why not tell us? What would it cost you - money or otherwise? We are the last generation that cares.

Is this tube necessary on an 8ba? Did OEM engines have them? I bought 2 8ba engines to build. Neither one of them has the internal tube. I am confused.

I agree. if you don't expose the valve seats, how do you check to see if the ports/seats are leaking?

No. It is an active crack, discovered with a pressure test and soapy water. I marked it with a Sharpie because it is very hard to see.

A good man could. No good men around here. I don't think i could. By the way, it is a very small leak. Takes over 2 hours to leak from 40 lbs to 5lbs.

Anybody have any advice on the repair of this crack? This is the center exhaust port of an 8ba.

That's how i found the crack in the exhaust port close to the manifold flange.

Thanks for the tips. I appreciate the help. I found a semicircle crack about 1/4" to 5/8" in from the flange area of the center exhaust port where the exhaust manifold bolts on. Total length about 1". Ideas, anyone?

I tested at 40lbs. had 20 lbs after 30 minutes had 13 lbs after 60 minutes had 9 lbs after 90 minutes Do i have a problem?

how much are these gm/8ba distributors selling for?

Gary: If i get into trouble with my assembly of my 2 8ba blocks, can i bring them to you? I need a good outcome on both of them. Thanks,... jack

I am pressure testing 2 8Ba blocks. how much air pressure should i use?

Are you saying it is too rich or not rich enough?

I have some power valves with threads that are damaged slightly. They test good. Anyone know how to fix the threads?
