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).

these cars ran hot even stock (hence the factory adding the air flaps under the car, and the shrinking of the red zone on the oil temp gage.. Youhave a larger motor so even more heat is expected.
the 40 psi on freeway is not too high a pressure, any less and I'd be worried.


you may need an extra cooler.

I would certainly run a thrmostate bellows. it is poor economy to not get one, you will have much faster engine wear with no warm up ability. would you be fine running your chevy ford or honda with the thermostat removed???? come on now and get that thing in there to assure longer engine life


as far as the high temps, you might also want to check head temps to see what mihgt be out of control.

leaves and crap can block the oil cooler, check that

my stock 2.0 also runs hot on warm days on long freeway drives. have to back opff else temp keeps going up (and pressure donw!) I have all tin in place and sealed, every thing right to optimize the stock system, yet it still runs hot, i even retarded the timing a few degrees, no change!

I will be adding one oil cooler to my car becuase of this, until then I drive easy when it is hot and pay close attention to my gages and slow donw if too hot.

I have a pile of these laying around now, let me know if you need one. I heard they are hard to find, but I don't have that problem... I go and look on my work bench and find 4 of them (IMG:style_emoticons/default/biggrin.gif)

Like everything I have sold it would be cheap.

I actually have a bellows, and I think it is even functional - though I have not tested it (and may have even given it away). my issue is that the flaps, which are supposed to fail open for cooling, twice failed closed. The bushings are crap and need to be replaced - and I need to drop the motor to do that , I think. I'd rather be driving now. if the motor fails after 50K miles from longer cold starts, that would still give me ~10 years of drive time - and by then I'll want to build a new motor anyway. Given that it is usually pretty warm during the driving season, I am not too concerned about my lack of a bellows. if i did a lot of driving in the cold (remember, my car has no heat), I would put one in for sure.
