Oil cooler install

[w-lewis]

I have a 351W with a 9qt oil pan and an oil cooler. Oil temp gauge needle rises to just slightly below the 140 mark, never exceeding that, causing me to question whether the gauge works properly. I've tried taping up the cooler opening and the temp rises to slightly above the 140 mark, but no more. Not sure where my temp sensor is located, but will check. Is my gauge wrong or is my oil temp unusually cool?

If that is the true oil temp, and never exceeds that, you need to do something about that, or start changing your oil more frequently.

The combustion byproduct acids don't start to boil out until 180.

Acid build-up in engine oil eventually destroys bearing metal in rarely driven cars.

Not having an oil thermostat is one possible cause of that.

Running an 8 qt pan and cooler on my 514 CI beast. Oil passes thru twin oil filters on its way to the oil cooler. On a recent 90 degree F day, after some spirited driving, oil temp rose to about 150 F. That's as high as it has ever gone. Granted most of my limited miles have been 20 or less miles, but the temps concern me. I have even installed a metal shield over the cooler, but not sure that helps raise temp very much.

Am strongly considering removing the cooler, and AN lines, and mounting oil filter on the engine block rather than the current remote location.

Next trip, I WILL shoot the pan with my IR thermometer, just to confirm what I fear - low oil temps.
