If really at very low pressure you would or should notice a knocking sound and that means engine OFF right away!!!!!!!!!!!!!!!!!!

You can get the actual pressure thru some fancy tools or just get it done asap or you will enjoy your new engine, T

You need to have pressure read with a mechanical gauge. This will rule out or condemn the oil pump. If pressure is good with mechanical gauge, problem is in sending unit, wiring or gauge.



Being way2old is why I need help from younger minds
