I have a wisconsin vg4d2. What is the oil pressure supposed to be? Mine is about 20. Also the compression is around 75 psi. Sounds ok when running and no smoke. Should that be closer to 100?
I think there was a high compression head option that would yield compression pressures up to 100psi. 75 sounds "normal". Oil pressure actually sound high according to this. https://www.google.com/url?sa=t&sou...Vaw3WrG_hflLED-x6ftNM6bDF&cshid=1595386545950
