Let's Play: Guess This Random Engine (oil filter needed)

[Babalonian]

Yes, this is a shameless ploy for knowledge/assistance from those wiser than me in these sort of matters, and I thank you very much for any and all help in advance.

Engine looks to be a Chrysler straight 6 (flathead?) I'm assuming, never had experience with one before and can't find any plate or recognizable to me.

So I'm just tryign to give her a well deserved and long overdue oil change (aka never been done), simple beans, but getting the right/spec oil filter would be swell.  I looked all over for a more traditional looking selfcontained canister type, and after looking all over concluded it had to be this other type I luckily have had no experience with.  Also I'm just figuring on some ol' fashioned 10W30 just to make it easy.

No documentation or tags for it that I've found, so this seems next best, I figure someone with a lot more experience has seen a hundred of these.  Low mileage as these things go, but in a couple weeks it'll be having its busiest weekend, and I got 20 other things going on before then, so here I am posting this in some down time this afternoon to avoid unecessary back and forthing and a good chance at banging it out in an hour this week.

Looks like Chrysler flat head six, circa 1950's.  Unless it is in some industrial equipment and then it could be as late as the 1970's.

What is the application for the engine?  Car, truck, forklift...?

Most industrial supply engine parts houses should be able to match the oil filter.

   Must be your Aircraft Tug no doubt. Best thing is to pull the filter and match it up.
  
Site I found can give you an Idea of where the S/N is on the engine and 1st letter designation.

A few airport tugs had chrysler hemi engines.......with a 1 barrel carburetor.

Low profile (Navy) tug.  Likely from around the late 60s or early 70s when I think Mexico was making a bunch of these engines (could also explain the lack of recognizable tags/plates on it).



I am aware I can pull it and go bounce around with it to a number of places until I find the right one/replacement, but this would be a very bad thing for this vehicle/tug as it is our primary/favorite/beloved tug and doing anything to it accompanied by the term "estimated downtime"... well, as I said, this critical maintenance procedure has NEVER been attempted/done on this extremely deserving and overworked piece of equipment.  Having the right parts on hand and to seamlessly complete this simple task (at around 6-7am local time this Thursday or Saturday) is the key to its success.

Yup, yup and thank you.  Going to dig around there, looks just like it and about the same sized filter (but slightly different in appearance though as you can see) and hopefully it lists the info (or ANY info I just don't have since this tug was a 2nd-hand donation to us).  Digging on after I pickup my lunch.  Most info I've found so far doesn't touch the auxiliary components of the engine beyond the block and banks (a sign there could/are many choice/variety).

Thought crossed my mind but I'm doubting it as A) those seem too early (1940s?) for what I'm dealing with and B) they would have some recognisable datum or plate on them, wouldn't it?  I'm thinking this was a later production (60s or 70s) hecke en Mexico.

I believe I'm looking for a (part#) Chrysler-1312603 or equivelent.  A little more checking to make sure, but about time now to just get down to it.

Most local forklift companies will have that oil filter in stock.

I lived next door to one and my best friend worked there for 14 years.

You will have the most luck with the larger and less consumer friendly shops........just a dark hole in the wall.
