Sudden Oil Pressure Increase
By John - 07/10/2002 5:08:24 PM; IP 142.177.79.98
Just for the curious, I changed to 20W50 mineral oil to finish the break-in and got a few more psi out of the oil pressure. The second time I drove the car after this, the oil presure suddenly increased. I now have almost normal oil pressure. I know the gauge is OK. All I can think of is a bit of "debris" from the rebuild caused the oil pressure relief valve to stick open slightly. The new thicker viscosity oil at a higher rpm caused the valve to open further and then go back to fully closed. But of course some damage is already done. Heaven forbid, but I might try to change the main bearings with the engine in the car after the summer is over.
This thread, so far...
