81 oil pressure

It varies, anything above 20psi at hot idle is OK on an old engine, a rebuilt engine with a standard oil pump would be around 60 at cold idle dropping to approx 40 as the oil gets hotter.

At 70 it would always be a bit higher but again the amount will vary, assuming the gauge is working correctly of course

Thanks for your replies they have helped alot. My gauge reads 60 psi when started and settles down to 40 ish. When driving reading is between 50 and 60psi.
