Hey guys, recently while at idle, my gauge sometimes warns me of a high oil temp, the temp varies dramatically and does not stay stable, well today even while driving the gauge would max at 320 for 4 secs then go back down to 230 and back and forth and so on.

I think i may have a oil leak somewhere around the rear of the block...

what do you think is causing these fluctuations?
during my drive home this morning something strange happened, there was a power loss from low end torque.. big one too... wonder if its tied with this problem..

I'm assuming your temp sender is on the block above the oil filter.

Could be several things. If it varies dramatically I'd first look at the wiring to the sender.. could have a "ready to break" connector.

second it might be time for a sludge removal treatment.

An oil leak wouldn't cause this unless you are constantly running at extremely low oil levels..

the oil temp sensor is located in the main oil feed from the filter in the block,


Id be looking to replace the sensor, connecting wire or gauge, oil temps CAN NOT jump rapidly between 230F and 320F its just not physically possible to have an extremely rapid rise and fall in temps, especially if the engine maintains fairly consistent oil pressure and flow rates, the oil pressure sensors up near the distributor. Id suggest verifying the oil level and pressure, it should be about 205F-225F at operational temps at idle and pressure should be no lower than 10 psi per 1000rpm
