im ok now with 5/30. i always went to heavier oil but never saw 75 on my fords.+1, I'd say 70 psi is acceptable cold. System max is typically around 100 allowable. The goal is staying above minimums warm pressure, while staying below max at cold. One of mine is odd that way, with 75+ on a 50°F cold start, and drops to 20-25 at ±1000 rpm when warm around 175-180°. Higher is again acceptable, realizing it does nothing for you while adding stress and some drive wear. Regulate your warm pressure with viscosity, and seasonally if required. Or, switch to a pump volume more appropriate to your application. Your call!
its still over 75 cold, never under.im ok now with 5/30. i always went to heavier oil but never saw 75 on my fords.
not in mood to do pump again!!!
now back to clutch trbl....
i have a 1/8 in valve coming to adjust but i wonder how much it would drop with just 1/8 copper?...might try. could pinch tubing to adjujst !!If you can adjust it down to aboot 25-30 lbs on a warm idle I'd leave it right there... 😉
did you read my reasons when i started this ??Are you just trying to trick your gauge? Are we assuming your gauge is accurate? Is 75 psi (if accurate) a problem when cold?
