Oil lines
I was told that the original oil filter does not do much, and that I could remove it without any harm. I would need to change the oil more often.
That said, my question is: Can I plug the fitting on the front crank cover and the one on the block or should I connect the two with
a new line?
Thanks,
Bill

Re: Oil lines
This topic has been thoroughly discussed on this web site and many others a thousand or more times. I would suggest you review those dozens of threads already written on the topic by using the site search function with the key words "oil filter".
The removal idea became popular when Mr. Cowdery's book the All American Wonder first came out. It was a suggestion in his book that created a sense of "If it's in Cowdery's book it has to be a good idea". Well it's not. Especially in the chain drive cam engines where the return oil helps lube the chain. Any filter is better than no filter at all. Even antique engines that do not use an oil filter have a fine bronze or brass wire screen that must be removed and cleaned every 25 hours. The misunderstanding arises from folks not understanding the partial flow oil filter system.
I'm afraid I have already said enough to turn this thread in the 10 page monsters this topic always turns into.

Re: Oil lines
I enjoy the version of "All American Wonder" by Ray Cowdery and my friend the late Merrill Madsen.
There have been close to a million 4 Cyl Jeeps manufactured with the same Oil Filter system since WWII. The military used the larger capacity Military Junior Oil Filter which was tried and tested under adverse conditions. They do work, the oil does get filtered and the proof is a dirty oil filter cartridge after a couple or three thousand miles.
Without the filter installed, there would be nothing to clean the oil as it circulates.
Remember, the Willys engine is 30's technology, which got a heavy duty Filter installed per Army heavy duty specifications.

You forgot to mention "All American Wonder" Volume 1 co authors Ray Cowdery and Merrill Madsen.

Re: Oil lines
Sorry about that. The second I typed the C my mind drifted off to Fred. Yes, Ray and Merrill certainly deserve the credit for all those oil filterless Willys running around!Joel wrote: You forgot to mention "All American Wonder" Volume 1 co authors Ray Cowdery and Merrill Madsen.
My apologies to Fred!

Re: Oil lines
You will note that the Jeeps belonging to Cowdery and Madsen are pictured in detail in AAW #2 and both have the oil filters in place.
Note on Page 94 AAW#1 that it was Tom Larsen, not Ray Cowdery or Merrill Madsen that had the negative opinion on the Oil Filters. Tom Larsen really did not understand what he was talking about. Note his remark "it is returned to the to the crankcase by gravity feed through the timing chain cover"- not so, there is Oil Pressure at the Oil Filter Outlet if one does not think so, they can disconnect the return line and put your finger over the oil exiting the filter with the engine running.

Re: Oil lines
The conversations I hear often refer to reading it in AAW but never TL said. Our society seems to take the written word as gospel without requiring any type qualification. Once a thought is type set and printed 8 out of every 10 folks think it is the final word on the subject simply because it got published.

Re: Oil lines
That is very true, and one must be very cautious with the printed word.

Re: Oil lines
I am going to put the filter back on. Anyone have a bracket, I cut the one I had up.
I suppose I could weld it back up. But if anyone has one cheap, let me know.
Thanks,
Bill
