Technical Chevy 292 oil pan gasket

I'm looking for an oil pan gasket for my 1963 292. It seems that the right gasket should be the Fel-Pro 1819. But the rubber piece that goes across the front doesn't have any holes in it, according to any pictures I've found of that gasket. But mine has 6 bolt holes. I also came across a break down diagram of the engine that shows that gasket, and it also has the holes in it. If I was to punch 1/4" holes in the rubber piece of the Fel-Pro 1819, I don't think it is wide enough according to the pictures I've seen. Does anyone have a solution to this oddity? Cheers

 

I think you'll find the oddity is that they redesigned the front cover and pan early in the engine's life, doing away with those bolts, because they discovered they weren't needed. The plan is to just use the gasket without the holes, and don't install the bolts if there isn't a hole for the bolt.

 

Rock Auto says FEL-PRO OS30126C1 for a 292 but it and the other three All show the front straight gasket.
O'Reilly's shows the same thing. https://www.oreillyauto.com/shop/b/...utomotive-truck-1968-chevrolet-c10-pickup-rwd

The Felpro 1819 is according to Felpro
Felcoid/Plus gaskets have a fiber sheet core and a latex rubber coating to eliminate potential leakage paths. The core material resists crushing and splitting, while providing excellent blowout resistance.

That may be what my 68 292 needs rather than cork.

Since the change is across the board with all manufactures I would imagine that it was a design change at one time.

 

Ohhh, ok. So out of curiosity, do you know what year Chevy did away with those bolts across the front section of the pan?

 

Are you finding that the cork on your front gasket is leaking?

 

I checked out Felcoid/Plus gaskets but it doesn't look like they have a gasket set available to replace the 1819 standard set.

 

I ran into the same problem with the pan gasket on my 250 recently. I just used a gasket punch and made the holes myself, worked fine and no leaks.

 

No. The 1966 shop manual shows all the holes, the 1974 manual does not. So some time in there....

 

I looked at pics of an engine I put together several years ago...it is a 1964, and I used the modern style gasket, with the old style pan and timing cover, and it wasn't a big deal to leave the bolts out. I guess some guys can't get over having holes without anything in them?

Chevy shows the same part number for the gasket in all the older parts books, 3930962, for car and truck applications from 1962-1975 (my newest book). And the number still shows up in listings for marine engines, etc.
