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).

Too much oil pressure could cause excess heat because the oil would be flowing too quickly through the cooler for it to take enough heat out of the oil.

Too much oil pressure could cause excess heat because the oil would be flowing too quickly through the cooler for it to take enough heat out of the oil.

I'm sorry but that is not correct. More pressure causes better thermal conductivity to the walls of the cooler. Heat is a continual flow from the engine to the cooler, moving it more slowly is not going to help, it is simply going to conduct less thermal energy.


edit: rather than just tell you "you're wrong lol" I'll link here to an explanation which is probably more helpful than a random post on an internet forum (IMG:style_emoticons/default/beerchug.gif)
