Hi guys, is this an aftermarket accesory or stock unit? I have filter # from prior owner but still curious. Looks larger in diameter tgan stock units I have seen.

Thanks!

Because of the color, shape of the lid and large wingnut holding the lid on I believe yours was probably sold as an aftermarket unit. In many cars of that era filters were an option and even into the early 50s add on oil filter units were frequently sold by parts stores and even corner garages or gas stations.

Here is an early photo of the 40 factory filter unit as was printed in the Salesman's Fact and Data Book. Same filter and canister shape was used for all engines with only the shape and routing of the steel tubing being different. I believe Packard used a unit made by Purolator in the prewar years. Not entirely sure who supplied the postwar filters but those had a flatter bottom and the inlet was at the side port rather than on the prewar's bottom port.

I do not believe the external look of the filter assy changed any in 40 but on the early 356 engines Packard did have issues with intermittent noisy hydraulic lifters. In the first attempts to fix the issue, Packard tried changing to a different filter element and then changed something inside the canister adding a bypass valve to route oil around a clogged filter. Neither effort met with much success. The final fix was a reroute of the supply and return lines but that was only on 356 engines. Postwar, as hydraulic lifters became more common by 51 all engines had adopted the plumbing change.

Thanks for confirming Howard.

Thinking Wix or NAPA gold 1010, prior owner ran Bosch 72127 which is fine but have a NAPA right down the street. The 1080 which seems to be the choice for a lot of Packard owners in this era seems a bit too small diameter wise.

Might also check out the Napa 1006 and see how the size compares. Some have used that filter in prewar canisters.

Glad you asked this question; I had exactly the same question on my 110's filter!

Thanks for the great info, guys.

(The filter housing on my '40 looks eerily like the housing on my Ford 8N that uses the Napa 1010)

I have one of those available from my first Packard, a 1939 Six, but not sure if original or not. The engine, which I still have, was from a 1940 110. The odd color of the filter was my own. Okay, I was a teenager and didn't know better!

I've seen these in several sizes.
For reference, my 39 has a purolator unit that looks like the one from Packard pictured and takes a Fram c-131 cartridge. The dimensions are Diameter: 3 13/16 Height: 4 13/16

Fram no longer makes this size but I have more than I will ever use in my lifetime if anyone needs one.

My 53 takes a different size that is still made.

My 39 Six has the type below (ignore the muck, how I got it-- need to replace head gasket and clean). I actually mistakenly went down the path of thinking I needed the cannister like referenced above. I actually wish I was able to use that style for ease of replacing, getting filters, etc.
