Engine: Bad oil filter mounting

[plee4139]

My 1956 Sky Hawk w/289 has a threaded stud which will not accept a new filter. Suggestions, please?

As 56 had the canister type filters it appears you might have a later engine or modified filter on the car. If the spin on filter is on the bottom then you can replace the aluminum assembly that holds the filter. This assembly bolts to the block. If your filter is a spin on on top of the engine then you can also replace the part the filter screws onto. A picture of where your filter mounts might be helpful to help determine which filter, if either, you have. You could also have an aftermarket spin on filter on the car. Both of the original Stude filter mounts are readily available.

Peter: Is the oil filter on top of the engine or underneath it?

If it is on top and is a spin-on type, it takes a Fram PB-50 or equivalent. If it is a spin-on unit under the car, it takes a Fram PH-25 or equivalent (or the longer PH11, if you can find one).

PB-50 and PH-25 are not interchangable.

In either case, if it does have a spin-on filter, it is not the original engine...or someone adapted a later, upper, spin-on filter to your car's original engine. BP

If your engine has a spin on type filter up on top, then is should take a Fram (or Luber-finer) PB50 oil filter.
That takes a 5/8"-18 thread per inch filter)

If you are trying to put on a PH24 (Luber-finer) or a PH25 Fram... That filter is for the later 'full flow' engine and takes a 13/16"-16 thread per inch filter.

Something to check out first....

Boy, Jeff; I sure wish AC and Fram had agreed on what a #24-suffix and what a #25-suffix filter would fit, eh?

Constantly confusing. BP

Actually Bob it's a Fram PH11 for the FULL sized (Real) Oil Filter, but I prefer the NAPA GOLD (WIX) 1049 full sized 1 Qt. Oil Filter for full flow Engines.

That way, you don't have to worry about no PH nothings!

Yessir... Two different companies.. Two different times... Now three different companies, two of them combined..
And the numbers don't have a logical meaning, anyways.
(Multiply your confusion by 6900 SKU's)

Right, Rich; thanks for the correction. Big fingers! . BP

The early spin-on filter base (part #1544217) was all aluminum and the threads were known to strip. This is probably what's wrong with yours. That filter base was replaced with part #1551374 which has a steel stud insert.

Actually, my mechanic found another filter (Hastings) which will fit.

So inquiring minds want to know, does that mean he just never had the Correct Fram PB50 or it's alternate Brand of Element and finally found the Correct Element or did he replace the whole Filter Base with a aftermarket replacement from Hastings?
