Before and after engine overhaul the oil
pressure after the engine warms up goes just into the red. They have
tried turning the pressure up but this seems to only make the pressure
go
up when cold. If the temperature outside is real cool the pressure
goes
over 200 psi. The engine builder said its in spec. I think there is a
problem somewhere. I want the oil pressure to run in the green. Does
anybody have any ideas on what could be causing this. I'm afraid its
going to blow the gage out one cold morning.

Sounds like the relief valve is sticking. That'll cause low oil
pressure when hot and high when cold.

I will ask the mechanic about this. I know they have replaced the oil pump
and a few other things before I bought it.
