I know we're not talking FEs, but when my engine
oil is close to 90 degrees Celsius my idle pressure, and I idle at around 700 RPM when the engine is hot, is around
15 psi. It comes up instantly as the revs increase.
This is perfectly normal for my engine. What would be too low at idle for a big FE? How 'bout less than 8 PSI.
And what was the Ford Service Bulletin solution for a flickering
oil light at idle when the FEs were really hot? Just turn the idle up a bit and it will go out.
