I'm sick and tired of the mess when replacing the PF131 oil filter in my '57. I am thinking of replacing the cannister with a spin-on filter.

This appears to be a simple conversion but I understand the AC PF35 filters are no longer available. What filter does everybody use as a replacement?

Thanks,
Pierre

Better yet NAPA 1060 Gold (they are really black not gold). They are higher capacity than the shorty filters and the label is easily removed so they are all black and nearly look like the original canister... Just make sure you get any old gasket material out of the block before installing the adapter....I did it in about 10 minutes...

you probably already know this...follow closely the instructions...some spin on adapters require re using the original by pass plate and new o ring....without it you will simply fill the new filter with oil and not the engine...you will be running on un filtered oil...good luck.....

With the old style canister filter (131 or later 141), when a new filter was installed, the filter comes with a square O-ring (gasket). It was imperative to remove the old O-ring before installing the new O-ring. This O-ring is what seals the can to the bottom of the oil filter boss.
When doing the spin-on conversion, this same O-ring is used to seal the new adapter for the spin-on filter. Frequently, some people install the adapter WITHOUT using the O-ring------------ A BIG OIL LEAKS RESULTS! Also, the original adapter with bypass valve is retained with the conversion (that's the part that is up in the oil filter boss and retained with 2 bolts).

Thanks to all for the good suggestions.
I just ordered the Mr. Gasket 1270 conversion kit and NAPA 1060 Gold filters. Should install all by end of this week.

Fram PH16 will work, too. If your kit requires using the original filter bypass valve, now is an opportunity to plug the bypass so that ONLY filtered oil enters the oil system.

Watch out for those things. I dont like the threaded insert that most of them have. I had the conversion on my car and the filter spun the threads up further into the conversion plate. The filter felt tight, but after i drove it a few times the filter fell off. Luckily i noticed the oil pressure drop immediately and shut the car off. I threw the conversion in the trash and now use the old canister style again.

You just have to follow the instructions and use some Lok-Tite on the big central threaded fitting that holds the filter. Just a few drops on those threads that actually go up into the engine will do it and you'll have no trouble. Keep the Lok-Tite off the threads that will hold the oil filter by all means.

I have been throught the "conversion.. massive oil leak.. remove the conversion" drill also. (mine was from the failure of the 1/4" screws to hold the filter tight)
I have mentioned this before here, but there is simply no way the conversion can mount the filter as securely as either of the OEM methods. (And, yes I know there are a lot of conversions out there that have not leaked...yet.)

Great suggestion. Why not cut off several bolt heads the same size as the canister bolt, paint 'em matching black, and epoxy one to the center of each black spin-on filter as you use them?

Frankie the Fink

I don't see how you can possibly screw up the conversion....its an O ring and two bolts. It's foundation is the same mounting point as the oil canister so if one works the other should certainly do the same.

My NAPA 1060 Gold filter suggestion was just so the filter is not such a big in-your-face departure from the canister's appearance. You can fake a bolt and even paint on a decal facsimile if you have that kind of time on your hands I guess.

I agree, its pretty hard to screw up the installation. The problem is that the resulting method for mounting the filter, will never be as secure or vibration resistant as either OE setup, which directly use the surface of the block to mount the filter or cannister.

Harry

Edit... Think of it this way: When you tighten the filter on the adaptor, you know its tight to the adaptor, but you don't know anything about how tight the adaptor is to the block. On either OE setup, its tight to the block..

I too had a conversion plate fall off of my 1964 while driving !

the only time that i have done a 'conversion', the adapter i used used a Ford spin-on filter and the adapter itself was (ya gotta picture this in your mind..) like all the side length of the cartridge type cannister cut back until about within an inch of the closed end (the closed end now being a flat surface), with a spin-on fitting in the middle.

this design has the best of both, the OD portion of the adapter seals permanently in the way as the old cannister to the same type gasket/o-ring in the block, and then uses a spin-on filter....

Personally, I prefer the OEM cannister. I still have them on both my cars. Not only do they have more filter area, you can see any accumulation of crap in the cannister. I suppose if you cut open the spin-on filter, you would be able to see the same thing.

AC Delco made a spin on adapter that used a Chevy filter, not a Ford style. I don't know if they still make it.

Speedway has the kit that will take a chevy filter, no by-pass on this so you need a good filter.

my 350 block came OEM with a spin-on filter mount, so i don't have any leakage problems....

instead of using the standard length spin-on filter, i use a truck heavy duty '2 quart' (i don't know if it really holds 2 quarts..) spin-on that seems to allow a higher oil pressure (probably due to more surface area and therefore less flow restriction).

yep, it looked like this one; but used a Ford Filter

I'm also wanting to do this adapter for my '56 since it will be a driver. I have a ton of RP filters already in my garage.

What adapter will allow use of GM filters? I don't want to buy Ford filters when I already have a bunch of expensive GM ones...

How about this one:
