Re: Noisy Lifters even though they are new

Don't these engines have an oil pressure cut off at 35 PSI? So would 40 PSI mean that the relief valve isn't functioning?

And if the dash light is blinking at 35 PSI, then that would mean the sending unit is bad, correct?

For reference, I installed a mechanical oil pressure gauge under my dash and it reads between 30-35 when first started, then will drop to 18-20 when warm at idle. When driving it's up around 25-33 depending on speed. I have mechanical tappets, running 15W-40 oil.
