89 mid cabin oil pressure

[mrrudely]

twin crusader 454's oil pressure
cold @ 700 rpm in neutral port reads 30psi starboard reads 40psi
warm in gear @ 800 rpm port reads 18psi starboard reads 40psi
no data yet at higher rpms
does anyone know what the readings should be?
I'm thinking of changing the starboard sensor
thx

I would check those readings with a known good mechanical gage on each engine first to double check what you are seeing, engines can have widely varying oil pressures due to build clearances, temps, age, there really is no hard and fast rule just a minimum pressure at idle.

Would not hurt to check with a mechanical gauge . But your in specs at that rpm Tachs could be of too
