Flathead pre-oiler - good, bad and the ugly?

[Flathead Fever]

In the real world nobody stakes the time to prime an engine. We didn't do it at the phone company but that was on "their" engines. On my personal stuff I always prime the oil systems before attempting to start them Don't forget to run the new camshaft at the desired break-in rpm for the duration suggested, usually around 20-minutes. I pre-fill the carb and anything else I can think of so that hopefully it cranks a couple turns and lights off. Then immediately take the rpm up to camshaft break-in specs. After the cam is broke then I'll idle it down and adjust the timing and Idel air fuel mixture.

Thanks! That’s the plan. Had the original cam reground by Pete out in WA. Went with the Isky 1007B? IIRC. ItÂ’s all stk other than the cam and overbore.

Went ahead and ordered this. Will replace the stk Ford setup with this for full-flow filtration.

There is no advantage, changing it to a (22 litres a minute) full flow filter! You are not going to be pumping it at a rate that will overwhelm the bypass filter. You only need to get the pressure up once! You may want to leave the pressure up for a while to force the air out of the oil pick up, but seriously 3 PSI would be plenty. I've done it with a funnel as in post #7.
It's a great idea, looks good as it is. I'm guessing you are going to pressurize it, then turn the valve off, then crank it over. Don't overthink it!

Have the rest of the modifications required for the conversion to full flow already been done? IIRC, the right most port in your picture is part of it.

tubman is correct! you must be 100% sure there is no restriction between the two unused holes (plugs)
someone has done some modifications to facilitate a 80% fullflow filter. part of this proceedure is to put an internal plug in the oil gallery. the internal plug goes between the fitting with the copper tube and the innermost brass plug
if the internal plug is in there and you run the engine it will be destroyed!

Ok. Good to know. Pretty sure there are no mods to those passages, but will now verify.

Why go to a "Full-Flow" system? With the maintenance and utilization of these vehicles these days, a "Bypass Filter" is an ideal solution for these engines. Back in the old days, we had dirt roads, bad weather conditions, and neglect; now we have paved roads, "Sunday Drive" conditions, and regular (sometimes overzealous) maintenance. In addition, a "Bypass Filter" will remove smaller particles than a "Full Flow" will. It's the perfect storm.

As to availability of filters, have you tried an farm implement dealer? The filter on my flathead Ford is the same as used in 8N and 9N Ford tractors and is readily available.

Hey Tubman . . . I wasn't recommending that he goes to a full-flow for the car, but was thinking that for his pre-oiler, the filtration system he has may or may not work - will depend on the pressure and amount of volume. Heck, why not try it?

I agree with you about the pre-oiler; volume is the key here. My first comment was in response to his post showing the remote filter mount; I wanted to make sure he knew that he needed more than that for a full flow system. My last post is just my opinion of which filtering system is best these days.

I use a SBC oil pump in a bucket of new oil. The threaded rod slip into the normal mounti8ng hole but stops short of the discharge plate I made. The other end slips over a bucket edge.

I drive it with my slotted pump driver. I made this one over fifty years ago. They can be bought now for little money. I drive it with an air drill which has the torque to drive it. Discharge tubing goes to correct fitting on back of flathead block.

Ok, finally an update. Really wanted to use the air tank, but then the comment about the oil filter had me worried. Wasn’t sure exactly what Bored&Stroked meant. So, came across a vid on BarryTsGarage on YT, where Ed Smith talked about not using the Ford filter. Said it was not a “pressurized” type filter and was only a flow type filter. He talked about the special “fitting” which I’m guessing is the “restrictor” and how there was there was no pressure inside the filter, and the oil would just drain back into the pan. I had no idea, just being familiar with “modern” type oil filters, I just assumed it was the same.
Also, checked the oil passages to make sure there was no internal plug inside the passage, and confirmed there was no plug.
So, cut the hose on the Home Depot sprayer, and just pushed on a fitting with a hose barb on one end and a 1/4 NPT on the other end. Added about one of the Lucas Hot Rod oil, and started pumping. Was going down slowly, so, cracked the flare nut at the oil pressure gauge, until I saw oil dripping out. Tightened up the fitting, and by the time I went back to the sprayer, it had sucked up all the oil, so not sure now if it pushed some air into the system. Also hand cranked the engine over a couple tim while adding the oil.

Also watched this vid, which just convinced me to go with the Home Depot sprayer. He had the same sprayer. lol!

Some pics. Couldn’t really get a good pic of the open internal oil passage. Used a wire as well to verify passage was not plugged..
