csx4910 Ron an easy test for the gauge is to remove the sender end and put it in a boiling cup of water. see how long it takes for the gauge to read this temp or come into the ball park. If you have a temp run use this to compare readings. It takes my
oil about 10 minutes of racing to get to 220F-230F max. This is an Aluminum Shelby motor. I have a Canton
oil pan in the car. Some senders need a good ground to get a correct reading in some cases also. Aluminum is not the best conductor of electricity or grounds. Does the sensor in the
oil pan have a white or red sealer on it? Red RTV is better than white teflon tape or paste. Rick L.
