too much oil pressure?, high OT on the freeway Options

[VaccaRabite]

My 2056 is getting elevated oil temps on the freeway. I am using a high volume pump, and seeing about 40 pounds of pressure on the freeway when my oil is up to temp.

What I think is happening is that there is too much pressure, and the oil is not being pumped through the oil cooler due to the check valve closing the passage. However, this is just a guess, as I don't have any way to test it. All I know is that when I am driving at revs, oil temp goes up and if I keep driving at higher revs the oil temps stay up). if I drop revs, oil temps fall back into place, but I can't do that on the freeway without building a lot of head heat.

Before I go through the trouble and expense of adding an oil cooler, I want to make sure that I have checked out the simple fixes first.

What do I do to make sure oil if going through the oil cooler? What is the point where pressure cuts off passage through the cooler?

All tin is in place, and fan housing flaps divert air over the oil cooler 100% of the time (no thermostat in place, so the flaps are always set to cool).

If you wanted Example A to apply to this situation you would try to determine how much ice you could melt with the beer, not how much beer you could cool with the ice.

You seem to have the concepts in your mind but you are misapplying them pretty badly here.

realred914 is correct here in pointing out that this is a closed system and we are dealing with an energy transfer problem. We are trying to transfer the most energy from the motor to the oil cooler in the smallest time possible.


The Bottom Line: More flow through his cooler is going to cool the motor more. You can try to bring up as much misapplied theory here as you want, but the bottom line is that oil pressure is not going to overheat his 914.
