Torquing intake manifold bolts question

Thanks...Dave

So, after 7 pages - going back to post 1 Dave, do you suspect a vacuum leak or are you just trying to take precautions against one developing? When you say "trying to rule out" that indicates you are trying to deal with an issue and a vacuum leak is one of the possible sources. Are you experiencing low vacuum or is there an engine performance problem?

Actually both. I just had the carb rebuilt. I installed it and took it for a ride. No more stumble when I get on it, but just cruising it will just die for a split second and the come back to life with a little surge. Hard to explain
I really don't think it is a vacuum leak, but it is an easy place to start. now that I saw all that corrosion in the cap, maybe that might have something to do with it.
Just talked to MSD. They recommended (2) 1/8" holes 180 deg apart in the base of the cap. this would also explain very heavy rust on the module. I purchase a new module last year but MSD said at the time it is an item that will work 100% or not work at all. So I held off doing it. Her said a light coating of dielectric grease should be fine if it is very light. He also said to put some on the reluctor for corrosion protection.No electrical there, just magnetic

FWIW, I have put dielectric grease on every electrical connection, every plug, every screw, you name it, and have done it for 40 years. I put it on spark plug connections, the distributor cap, the rotor, everything. It's great. It will never interfere with any connection and any threads that say "no, dielectric grease is an insulator and will block the electron transfer, blah, blah, blah..." is just a crock o' shi*. Put it everywhere, just don't glob it on.

Been busy with house projects so have not got back to the car yet.
I had a thought this morning that I never considered when re-torquing the Intake. Some of the bolts were looser than others so I did get movement. Are any of these bolts thru bolts that hit coolant and are installed with RTV to seal them?
Just a thought on creating a new problem by moving them and disturbing any cured sealant possibly creating a leak somewhere.

None of the bolts hit water.

Cool, that is a relief...thanks
