Just to clarify the bore size of the jet was related to gear drive cam engines only and the problem was with overheating the # 1 ROD bearing.
The Old issue over the filter removal started with one of our jeep books that proclaimed it was the right thing to do with the chain drive cam WWII jeeps and early 2A's. Hinted at #1 main oil starvation issues. The author withdrew that recommendation many years ago. _________________ Wes K

Wesk, the best i can answer your question is this Unusual Trip occurred i think around 88-90 based on his old receipts and title transfer. He gave me every receipt he incurred in the reconstruction. Furthermore i have pictures of my jeep in the Overland Plant. How neat is that!!!!! This guy would stay locked up on weekends in the plant and work on his jeep. pretty cool story. So i guess the ole saying "is not what you know is who you know!!" helped my buddy out.
That's a nice little commercial shop that seems to specialize in Willys/Kaiser/Jeep service. There are several carrying various Willys, Willys America, and Willys -Overland titles still doing business today.
The Willys Factory is in Toledo Ohio and was a huge steel, concrete and brick facility.
Here are a few photos of the Willys Factory:

1998: By the time ground is broken for Toledo North Assembly Plant next to the Stickney Avenue factory, Jeep Parkway is made up of 62 buildings covering 4.5 million square feet.
This photos shows the demolition schedule the plant has followed over the years.
The plant property today.
Ron Szymanski managed the Jeep Museum at the Toledo plant for many years. Until it too was demolished several years ago. _________________ Wes K

wow! love the roof top shot. Looking through the receipts.. Willys Overland MPL?...so that makes sense.. his buddy worked for a "shop" that specialized in Willys Jeep restoration...
OK.....thanks for history lesson.......Now question and advice please
Is it worth the $$ for me to pay someone to tear down the engine and check the spray nozzle jet diminsion.........or carry on like i have been doing? Will it eventually tear up my motor even if i change my oil every year with about 2000 miles on it?
side note....changed my oil and tweeted the carb on ole girl will run 60 mph on highway with canvas top.....is that good? _________________ 1952 M38
That Minneapolis outfit was the originator of the oil filter tale.
I would run a filter. It's up to you on your jeep. If you don't have a problem yet and the engine serial is MCXXXXX or RMCXXXXX then it would have come from Willys with the correct nozzle size and the oil pressure loss at that #1 rod bearing would not be an issue. One way to check is to read with a DIRECT MECHANICAL pressure gauge the actual oil pressure at the rear of the gallery and then at the front. The fitting behind the fuel pump is difficult to access.
The numbers rose into the 6 digits around Jun/Jul 1952. They just used up all the 5 digit numbers. The switch in jet size was implemented before the MC & RMC engines came out at CJ3A eng serial 3J-166871. That is why I said if you have a correct MC or RMC serial you should have the correct jet already. _________________ Wes K

Thanks Wes . previous owner said he put a "BB"? in the line to stop oil. So i got to find the BB and remove and inspect my oil canister and make sure it has all the parts. Initial inspection looked to me like the filter was a small minnow bucket!!! _________________ 1952 M38
