I have a 1940 Mercury with a bypass oil filter. Were these installed at the factory or were these filters dealer installed? My question concerns the return line location and attachment method. The return line on this car ends with a banjo type connector, passing oil through a hollow bolt on the distributer mount. The attaching point of the return line is also the attaching point of the ignition condensor. Any leak blocks a good ground for the condensor and creates poor engine performance or no performance at all. Where were these lines properly attached to return oil to the pan? chascwell

They usta repo a double hole dipstick mount which fed return oil to the pan.That is the best place to do this.You will also get leaks at the fuel pump stand if used there also. Not sure if their available anymore. ken ct.

Oil filters were an option in 1940. Thus, you may remove it and not loose any judging points on the concourse. There were two authentic routings for the return line in 1940. the early design utilized a hose that was routed to a special bolt that had replaced the left fuel pump to pump stand bolt. That routing was replaced in early May, 1940. That's the one you apparently have. Regardless of the routing you utilize, properly installed with the correct fittings, there will be no leakage. In my opinion, get rid of the filter. They do very little, having a rather poor design. Instead, change your oil frequently as no doubt, you do now... returning oil to the oil pan was not featured until 1942 I believe. Certainly NOT in 1940.

Thanks for the replies guys! I guess, as we used to say, these filters clean some of the oil part of the time! chascwell

Chas, Kube's answer is correct as to what was original to your car. His opinion on the worth of an oil filter is exactly that, his opinion. My opinion is that the oil filter does what it was designed to do, that is: It filters ALL the oil once every five miles, and it also contributes to engine cooling, as the oil system itself is contributary to cooing.

If you want to continue using your oil filter, you can replace both of the copper crush washers at the banjo fitting to stop the leak. I do not have a filter on my 40 Mercury as I found it to be an expensive hassle to maintain it. I believe that you should change the filter with every oil change. I change my oil at the beginning of the driving season and every 1,000 miles during the season and again before storage. The filter requires that you remove the element and have something to put it in to drain, without dripping all over the engine compartment. Then you have to remove all of the remaining oil and clean out the housing. Now you have a bunch of oily rags to dispose of and a dirty filter to dispose of. I agree with Alan that all of the oil will pass through the filter and that it does add to the cooling of the oil, but I do not believe that the poor quality of the elements available do much to clean the oil.

Having grown up servicing a "fleet" of flatheads with oil filters, I tend to side with Alan. As for the hassel of dealing with the oily mess, it is no different than any contemporary oil filter system on any brand of the era. We never used the little drain plug at the bottom of the housing, but rather used a suction gun to empty the housing. As to the filter media, today's replacement filters such as the Wix 5106 are far superior to the cotton waste-filled Frams of the 40's & 50's. I doubt if many antique tractor buffs would consider removing the very same system (and filter element) from their 8-N's. If you "autopsy" your Ford's partial-flow filter after an oil change by cutting the canister open and stretching out the media pleats, you will see just how much it has trapped. All of that debris captured did not continue to circulate through the bearings, as it would have with no filter. These filters did help; perhaps not to the degree that a modern full-flow filter does, but anything that can delay motor rebuilds due to combustion byproducts and ingested dust caused wear is to me, a good trade-off.

If anyone doubts how much oil reaches the filter, just forget to secure the lid! Don't ask how I know that.

Just for the heck of it. My 2008 Saturn has a cartridge filter. Changing it is exactly the way TomO described. The more things change..the more they remain the same!

Stroker, I still don't want to deal with the mess, and I don't trust the grease monkeys at the local oil change facility to change it either. They make a big enough mess just changing the oil and greasing the car. I don't get under my car these days as I do not know if I could get back up again. As I told Chascwell, he can continue to use his filter if he changes the copper crush washers. They are available at his local parts house. I don't intend to put my filter back on. Tom

Tom: No offense intended. I can no longer physically function as I did in the 50's, so I can certainly relate to having others mismanage tasks I learned to do properly so long ago. As to the copper banjo washers, I learned a trick in my aviation wrenching days that works well on solid copper washers. String them over a piece of coat-hanger wire or welding rod and heat to a dull red with a propane torch and then quench in water. This will anneal the copper which has become hardened due to thermal cycling. The annealed washers will once again conform to the sealing surfaces as well as new.

About any local auto parts store should be able to order this filter.

I agree with Stroker on the quality of the WIX5106. I believe it to be the best element available, and should be in stock at many NAPA auto Supply stores, particularly those in farm country. Alan
