Accusump E.C.P valve or Manual?

[RICK LAKE]

Tom Wells Tom that's a bull story with the Canton guys. We have 2 different motors, My FE motor has longer side skirts than your 460. My oil returns from the heads are smaller. The ONLY time I everyheard a company tech say to run a motor underfull was 1/4 mile racing. Canton, Moroso, Aviaid, and Millidon all say this is OK. They are not paying for your motor to get rebuilt. Think about this, If this was OK, everyone running autocross and roadracing would be running 5 quarts of oil instead of 7-13 quarts. As far as the distributor driving the oil pump, there are 2 thing to take into account, first is having the right gear combo between the 2 gears. This depends on what material the cam gear is made out of and matching it to the correct distributor gear. I have seen many times over the wrong matchups. Harden shafts to drive the oil pumps are very important, IMO. The other thing is having a steady flow of oil going on the contact point between where the 2 gears meet. This is a machine shop extra. Knowing how much oil to spray in this area. 8 years of racing and my gear was just fine. I am running the composite gear to see how well this works out. Tom, it's the little things that help and save a motor to run along time. Will a HVHP pump put more stress on the gears, YES. But if you know what to do to slow down or stop this problem, the issue becomes mute. I would have to look at an oiling system in your motor. I am sure there is a way to lube this contact point all the time. Rick L.

Rick,

I verified the "quart low" myself. The problem got less when I did that, but not by enough.

There is a mod for the distributor gear oiling for the 460 here: http://www.highflowdynamics.net/?

Pick the top selection on the left side of the page.

For some reason the oil pump drive system on the 460 is different from the other Fords in that it is more frangible (always wanted to use that word on CC) than most other engines and if you are building one of these you need to pay close attention to this area.

I'll do this mod on the next engine for sure!

In the meantime, once I got the oiling issues under control (read: Accusump and correct distributor gear location), I have 22,000 + road and track miles on this engine and it's still OK!

Tom Wells Tom I'm not a pro builder but been there,done that with different motors. Thanks for the site on the oiling mode. Here's the thing, 1/16 of an inch is hugeYou want to spray the area not flood and loose 10-20psi of pressure. On my motors, for the timing chain to get lube, .015" with the hole looking like a spray nozzle. This fans the oil out. Over time the hole will get bigger but this was a new motor to 50K. Oil for the distributor is about the same.020" Same thing, spary the oil but not flood the area. I'm not sure what your FRANGIBLE issue is?? Location, oil flow, Oil shaft issues, or just the old engineering sillyness?? I know you run 1 quart low. That scares the crap out of me. Different motors different modes. Rick

Rick,

I personally do run one quart low, but after I installed the Accusump I fill the engine up to spec

Good info on the hole size for oiling BTW!

Rick Lake,
Tom is correct I have the same motor and pan. Canton could not correct the problem and had me purchase a accusump.
Canton sucks!!!!! They have a problem with that pan design and won't fix it.
