Thanks for contributing to this thread, it gave me great info. I do have a couple of questions?

I recently purchased a 1939 Mercury eight chassis with a "running" 239. I plan on using it in a 1941 ford Tudor project I have. So I built a stand to mount the engine and radiator so I could run the engine and see what it needs. It has nice compression in all cylinders but when I pulled the oil pan and filter it had a lot of sludge. So I cleaned it all and ordered the filter for the canister. When I got the filter I went to install but I could not see how the oil could drain. I cannot find the two .063 holes in the tube and on further inspection the inlet does not seem to be a restriction of any sort. Looks like a .25" fitting. It appears that when it last ran the filter path was plugged solid so oil must be in bypass. I'd like to have a filter when I crank this engine up and test run.

So my question is can I buy the inlet restriction fitting and can I just drill new return holes in the tube?

Any insight or suggestions would be appreciated.

Thanks in advance, Dan
