SBC O rings on Dist?
do the O rings really work/help or was this just an MSD gimmick?

Re: SBC O rings on Dist?
it is a reasonable question. I have never installed them but on the other hand, I expect it will not hurt anything.
Yet, I am considering all the Chevy engines running without them |

Re: SBC O rings on Dist?
Just a thought,
The stock Chevrolet blocks and distributors are cast iron with tight clearances on the OD & ID......... MSD is aluminum and is a fits all...... The "O" rings couldn't hurt, but only help getting oil with the least amount of leakage to the lifter galley... Just my 2 cents, Bob

Don't get all wadded up, I just had a brain fart............. But everything else is correct...... Do it or don't do, it works either way????????????????? Again I revert back to.........What could it hurt it could only help Have fun, Bob PS: My engine oil primer is made from an old cast iron distributor body...... But that's probably 50 years old.......... Just sayin'

Re: SBC O rings on Dist?
I've heard that bronze distributor gears wear less quickly with a little groove in the distributor body and no O rings. That arrangement seemed to help the looks of my bronze gear.

A + Ron
Use the top one and leave the bottom one off. I like the slot leading the gear contact slightly. Gear gets a little oil.

Re: SBC O rings on Dist?
I have always used a slot filed in the bottom, aimed at the dist. gear. and have wondered about using the top O ring and no bottom. once again Adger the experienced one, confirms. thanks guys.
