Distributor gasket installation.

As many of you know, the 700 455, and probably most if not all, distributor takes a "O-Ring" around the shadt. Does this eliminate the need for a gasket at the timing cover?

 

I've never used a gasket with an O-Ring.

 

I’ve only ever used the o-ring around the lower portion of the body. Never anything underneath the lip that sits on the timing cover, if I’m understanding your question.

 

There is an actual o-ring groove in the dist.

 

Yes, I’m aware. OP mentioned a gasket. Never seen one on a Buick. My old Pontiac used a gasket, no o ring

 

I use a little grease under the flange

 

I was confused about this a few weeks back too. When you Google it, a couple gaskets come up.

Did the Skylarks and Specials come with the Chevy 4.1L Inline 6?

Maybe those take a gasket and not an O-ring?

 

Ahhh, I always forget about the 250 CID inline 6 cyl in the Skylarks. Yes, that paper gasket is correct for that application.

Chevy built engines use a gasket.
Buick built engines use an “O” ring.

 

Just didn't know if Buick took both.

Thank you to everyone that helped out!
