I have used different springs in the oil pressure relief valve ,does not help

What help would you like?
What oil pressure does it make now? at idle and at 1500RPM

Does this engine have the reverse reduction gear on it that is shifted by engine oil pressure?

I gave my manual to the fellow that bought my engines, but I'll try to remember what I can.
