No leaks...I hate a leaky engine and make sure I fix and prevent any....Where is the sender on the 3vz..I may just swap to a mechanical gauge and check the pressure manually..it seems odd because to me if I had a problem it would be the reverse of the way its happening..it should come on at idle, and go away at higher RPM's where the pump is turning faster...?

now why didn't I think of that...
theoretically yes, assuming the sensor AND the oil pump is still good...
as far as where that sensor is on that motor, that's outta my field... imma 22re guy, sry...

Alriht I connected a manual gauge to it today and at idle..it shows 80 psi...rev it up it goes to around 100 psi..very high when compared to the Haynes manual specs...!

These pressure numbers are pretty much what people around here get for the 3.o at start up and initial idle. Goes to 100 with rev. Once settles, down around 25.
The wire coming off the pressure sender is prone to bend/break at the sensor end. For pics on all this, see my recent link:https://www.yotatech.com/forums/f116...ensors-153167/ , I am going to update with my own pics when done (soon)

Just checked the fsm
3vze: 93 fsm says 77 psi on the relief valve
22re: 85 & 93 fsm say 64 psi on the relief valve
3vze: 93 fsm says 77 psi on the relief valve
- 4.3 psi @ idle
- 36-75 psi @3k rpms
