Oil Filter Dilemma?

Recommended Posts

Hey Crew.

Dropped the oil out of the "48" and pulled the filter out of the canister. I believe my old filter to be the wrong cartridge for my canister? I read back in the archives and am still not sure what filter I need or even if I have the correct canister. I took a few pictures of the old filter and a new one I ordered. Problem is I do not think the new one is correct either.  

The old filter had 11/16" holes top and bottom to fit over the post in the center of the canister. The new filter has a 9/16" hole in the top and a 11/16" hole in the bottom??? The oil post is 9/16". I don't do metrics or thousands, just an old truck driver here. 

Anyway, long story short I'll use the new filter, it's a Wix 51080. The old filter was a NAPA Gold 1080. I found a site that lists a filter for a "48" Plymouth but not the brand. I will attach a link to that site.

Package of (2) oil filters for so-equipped 1941-48 Plymouth; 1941-48 Dodge (passenger cars); 1941-48 DeSoto and 1941-42 Chrysler (See our other listing for 1946-48 Chrysler). These are getting scarce so its good to have a spare or two on hand Replaces OE p/n's 852758 - 861032 - 1121689 - 1123151 - 1123152 - 1124594
I am going to head to Car Quest Monday AM to see what then can find by the numbers listed above.
On the lid of my oil filter canister you can almost make out the old part number 1123152. In the second picture is an oil filter for the "52" M37 Dodge motor. I get them from VPW in Fairfield Iowa. 
I have to believe somebody makes a proper fitting filter for my canister. The challenge is on!  :D
1948 Plymouth Special Deluxe Oil Filter canister.     M37 filter left, Plymouth filter right.              4 1/4" tall overall.                                    4" canister body only.              Oil tube in center of canister is 9/16".

If you are indoubt of the correct size then measure the  diameter of the inside of the canister then measure the center rod diameter then measure how deep the canister is in capacity.  Then go to your local napa store with these measurements and they should beable to find something close that willfit.  Might not be perfect but it will work to filter the bypass oil.  I use the NAPA 1010 gold filter in my AC canister and it works for me.

Thanks Guys. I appreciate the input.

I'm going to try Car Quest first. Our NAPA is,,,,,, well, er, I will try Car Quest first.

 What I don't understand are the same size 11/16" holes in the NAPA Gold 1080 (old filter) , and the different size holes, one being 9/16" and one being 11/16" in the new  WIX 51080??? ,  It's been in there a long time. "Yuck"

Anyway I will use the new Wix filter this time and do a bit more research.  Did not know Wix supplied NAPA. Also the center oil rod is right at 9/16".

Thanks Guys, to be continued.

Hip Hip Hurrah!

A few more hours in the shop and a lot more cleaning I found the WIX 51080 to be the correct filter for my canister. You Fellows were exactly right. The inside of my unit was so disgustingly dirty I failed to notice the bushing on the lower part of the oil pipe. The filter fits fine nice and snug top and bottom. Yippee. :D 

Smooth Sailing Now!
