351E Spin-on oil filter vs canister

[GMCNUT]

Hey guys - need a little help maybe - I have a spin-on oil filter adaptor off a spare 351E I have, and I want to install it on my 66 Suburban's which came with the exact same engine, but for some reason did not come with the spin on oil filter like the other 351 did (not sure why one 351 would have it and one would not?)

So I need to buy a gasket for the spin-on oil filter adaptor, and was wondering if anyone has the right part # or a source to get this gasket without buying a whole engine gasket set if possible - also wanted to ask what the correct spin-on oil filter part # is and if its readily available at most part stores, or if I need to order that too?

Thanks in advance - Steve

Steve,
It is really quite easy to make flat gaskets for things that are not particularly critical, such as the oil adapter.
Get a piece of flat gasket material from NAPA (or your choice of local suppliers).
Trim to close to the the needed size and tape it over the flange for which you wish to make a gasket. In this case, use the adapter assembly, preferably, clamped in a vice.
With the gasket material flat against the adapter, just lightly tap against the gasket material, around any openings, with a small hammer ( a ball-pien hammer works great). When done, you should be able to see an impression of the edges of the openings on the reverse side of the gasket material. Just cut out the unneeded parts, and you should have a very usable gasket.

This works very well for fuel pumps, thermostat housings. water outlets and various other relatively simple applications. With care, it can be done with more intricate designs.

I made one,pretty simple.

Perfect - thanks for that advice - I started to do that very thing, and then wondered if there was a Fel-Pro gasket just for this application and wondered if maybe that would be better some way so wanted to ask in case that's what everyone else was doing.

So would you also add any black Permatex or just go with the plain gasket? don't want it to leak so was thinking of adding a paper thin wipe of black glue over it too....thoughts?

I don't think it would be necessary, but it would not hurt anything, particularly is the mating surface was not scrapped clean.

Run a flat stone over the mating surfaces. Then use something like hi tach spray or spray copper coat on both sides of the gasket. I have seen to many engines destroyed with silicone type sealers. For some reason people appy to much and it gets into the oil passages.

very good - so anyone happen to know the part # for the spin on oil filter itself?

The standard replacement oil filter for the spin on setup would be an AC PF-24 filter, other would be the longer PF-31 which is no longer available but the Fram PH-11 would be the same for a little more capacity over the PF-24. I use a 1 1/2 quart capacity filter from Wix #51831 also 1831 from NAPA, it's actually a filter for hydraulic equipment but is exactly the same as automotive filters.

Thank you Pete! Will get one of the 2 bigger filters on order

The bigger filters have always been my choice, only helps to have a little more capacity
