4psi idle (bad) and revving to 3k does what, you didnt say.
what was idle RPM 800 or 400>?
the answer is different by hot and cold oil
and oil type, no type stated (do not say brands) 10w30?
running 0w are you>?
and is as low as 8psi hot. at idle ,that is if idle speed is at spec.
is it?
and 3000 rpm would be like 25psi hot, and more cold.
the max pressure will be the pump regulator value.
here is the sensor spec.
The sensor closes when the oil pressure drops to between 4-7
psi (28-48 kPa).
the oil type and bearings clearances (in total) dictate pressure.
3,1 CPC engine spec is.
This truck idled way too fast before the water pump and battery replacement. Just wanted to clarify that fact.
I checked where the throttle cable hooks up to the throttle shaft. The mechanism does not seem to be held open by any adjustment screw. Is it possible that the throttle shaft is twisted internally in relation to the external linkage? Could there be two parts to the shaft that are now misaligned?
