Was vexed during the last few weeks by the oil pressure gauge, reading 75-80psi, which is quite high. That was after installing a new oil pressure sending unit and gauge!
Finally installed a good old fashioned manual gauge from Carquest. It reads 65psi, which is more reasonable. My izuzu parts dealer recommended it; but several others dismissed this as “outdated” thinking. But it is great to see a second “opinion” on what is happening inside the engine.
The importance of keeping good oil pressure is paramount. So this is a happy new addition to Mr. Izuzu PowerPlant.
