I have a 1.8 silvertop in my Lotus Europa. The oil pressure drops off when hot.
Smiths electric gauge, swapped sender still same. Pressure switch is a 20psi job and light is flickering.
The engine was a Ford short motor, crank has been ground 0.25mm u/s. Had it stripped and measured, all good. Oil pump and bearings look fine.
what is a normal hot pressure for these? Am I chasing shadows?
cheers
