rebuilt engine everything new mechanical oil pressure gauge on startup engine warm 80 psi. Started backing her out noticed oil pressure gauge 0.proceeded to back out oil pressure back up to around 70-75. Let it run and watched gauge fluxuating 0-80 psi. Its an HP high volume pressure pump. Believe its a milodium pump. Is it supposed to fluxuate like this because of the pressure relief valve and pump or bypass?
65 satellite 4 speed, if that means anything. Any help will be appreciated.
P.S. Love this website.
