Engine: 2.8L V6 the felpro 70800 (stock replacement) distributor o-ring isn't sealing %100 and its leaking oil out of there I just need a slightly fatter o-ring.
ALSO: the OE distributors come with a distributor sealing gasket. its just a flat standard gasket that goes in between the distributor and where it mounts to the block.

Rodneys thicker O ring solved my oil leak just use some vaseline or other lube when you sli[p it in,,bigger is better ! & when you set the timing check for tight flashes to much mark wandering indicate,s loose timing chain

Weird that a new, stock (IE, soft and pliable, not brittle) O-ring won't seal. Be sure you don't have a scratch or gouge down there by the base where oil might be getting by.
A gasket from a Chevy V8 fits, and yes, lots of people use them, but I'm not aware of any 2.8 motors that used them from the factory; just the O-ring. If you do use one, double-check your timing afterwards in case you've squeezed the gasket when you tighten the distributor hold-down bolt.
the motor was rebuilt, it has about 15k on it right now, so I don't think the timing chain is an issue right now.
ALSO, if anyone has ever taken out an original distributor, there should be a base gasket that goes in between the block and distributor, I'm assuming this was supposed to work in conjunction with the o-ring to help seal.
I'll wait for everybody to chime in. but regardless, I'll need to get an o-ring

The SBC doesn't use an O-ring, just a gasket. But if you're finding a gasket on your 2.8, its because someone put it there - a previous owner, or more likely, the engine rebuilder. Like I said, there are many who use it - and just as many that do not. It didn't come from GM with a gasket.
The O-ring Rodney sells is the correct one. Buy it. Its also useful on millions of other GM cars, where the old distributor base serves as the oil pump drive. They leak just as bad if the old brittle O-ring fails.

No there should not be a gasket between the distributor base and the block. Other engines do use them, the Chevy 2.8 does not.
To the best of my understanding, the one Rodney sells is not and SBC o-ring, it is a standard o-ring that is made from a better grade of rubber. It will seal better and last longer than any o-ring you'll get from an auto parts store.
