Oil filters 101

[greg g]

Your assignment should you choose to accept it is to determine which of the following is the correct filter for a 40's to 50's era Dodge/Plymouth flathead 6.

[greg g]

or could it be one of these?

[daddyo23]

I don't know if it's correct but #2 in your first post looks like the one on my '48. Wayne P.

p.s. But I know it was an add-on, so, maybe the pic with none is correct.

[greg g]

or perhaps from this selection. I believe there are two correct answers.

Note to Mike W since you must have gotten to busy to post the photos of your oil filter to let me decide if your's was correct or in your words OEM (even though I assured you it was) perhaps with the above examples in evidence you can now take a moment of important time and make an educated decision on your own.

By the way in taking some time to gather some knowledge, I had the opportunity to chat with a fellow who was a retired Chrylser purchasing executive, he pointed out that the term OEM is actually quite misleading and leads lots of folks to chasing their tails. It seems that large companies like Chrysler contract with several suppliers of parts to be made to their specs. So all these various contactors would supply parts that were made by Original Equipment Manufacturers even though they would be from two or even several more sources. Keeping a supply of parts to support Factory Installed Parts on the assembly line had many Original Equipment Manufacturers in the supply que.

So if you get into even a narrow search for an OEM item, it might lead to several trails with several forks. Anyway happy chasing.

Do I need to post the 8 radiator cap photos also????

[Captain Neon]

I think it would be invaluable to post all the various radiator caps.

I'm still looking for those people willing to part with $35K for a stock P15 coupe. I'd be happy to help them out.

It'll take more than that to get a rise out of Mike, he will just type out a unreadable response and go on his merry way...oblivious. I on the other hand thank you Greg, for more photos for my archives.

My 50 Plymouth had #2 in the second batch of pictures when I first bought it. I changed it to a replaceable canister fram filter like #1 in the first batch.

Here it is installed

[greg g]

Probably should have taken pictures of the hose clamps also................

Greg;

Send me eighty bucks (non refundable) up front and I will research (for one hour) and find an answer to your questions. Deal, or no Deal??????????

[Don Coatney]

Wait a minute!

Hose clamp research is extra. Will cost you $137.00 bucks an hour (up front and non refundable) for an answer to your questions.

How much does your mechanic charge? I might be able to beat his charges if and only if they are reasonable for someone who has never seen a P-15 in full dress:cool:

[Frank Elder]

Not fair! You documented your build beyond belief:D

[Plymouthy Adams]

Don, Greg, after reading your entries and as such reporting back that both are well written and informative..I feel this should net me some sort of a customer survey fee.. you can submit those funds to my paypal account and I will not even try to get you to pay the transfer fee preminum.

What a deal....eh! (for our Canadian friends)

[RobertKB]

What a deal....eh! (for our Canadian friends)

Tim, we can make you an honorary Canadian...........for a fee, eh.

[greg g]

Check your accout balances, I believe I transferred enough Latvian Kronars to cover your fees. Don just keep the money, I am not in the market for hose clamps and have done the requisite research and drawn conclusions.

[Don Coatney]

Greg;

Reconsider! I need to build my retirement funds on account of it aint big enough:eek:

[greg g]

Sorry you're the one who's still working, guess you will just have to work longer.

[Rollie���]

here's the filter housing off a '53 Plymouth that I'm going to use:

[Rollie���]

and the "original" style filter that came on the car:

[greg g]

I believe if you look closely that is an aftermarket replacment, and not an original piece.

[Frank Elder]

If none of the 218/230 engines came with oil filters from the the factory and they were installed by the dealer or the owner, doesn't that make them all after market? Or did the dealers install mopar specific filters only?

It would be interesting to find out for once and for all which years/models had oil filters from the factory.

I know that in 1933 the original PC ("Plymouth 6") and the later PD ("Deluxe 6") came from the factory with filters. Not sure about the PCXX ("Standard 6").

I understand that in the later 1930s the Standard/Business/Roadking models did not have oil filters while the DeLuxe models did.

Would that have been true in the P15 era: The low end (Deluxe) without filters but the high end (Special Deluxe) with filters?

[Frank Elder]

Where's Mr. Watson? He'll Know:D

[Andydodge]

My 1941 P11 Coupe arrived at my door with no oil filter and when you consider that this car had been "restored" about 5-10 yrs ago you have to wonder what "restored" means, lol..........it has a beehive filter on it now and regular oil changes.........andyd

[LAKOTA169]

This is the filter that was on the '50 P20 engine in my '37 when I got the car.

This is the filter that is on the P23 engine in the car now.

My 1941 Canadian Dodge came to me (in 1973) with a FRAM PB 1/2 throw away type filter. Whereas my '40 (in family since 6 months old) had a cartridge filter (canister colours not recognizeable), since replaced by a FRAM aftermarket cartridge filter.
