Envoy 4WD V8-5.3L VIN M (2005)
Engine Oil Pressure: Specifications
DoD
^
Displacement on Demand Relief Valve Oil Pressure - as Measured at Oil Pressure Sensor Location
Metric .......................................................................................................................................................................................... 379-517 kPa Maximum
English ............................................................................................................................................................................................. 55-75 psig Maximum
^
With the engine running and the lower pressure gage (2) measuring below 379 kPa (55 psi), both gauges should display the same pressure
reading. If the readings are not the same and the lower gage (2) has a higher reading, the DoD oil pressure relief valve is stuck in the open position
or the valve lifter oil manifold filter is plugged.
^
With the engine running and the lower pressure gauge (2) measuring above 379 kPa (55 psi), the upper gage (1) should display no greater than
379 - 517 kPa (55 - 75 psi). If the reading on the upper gage (1) is greater than 517 kPa (75 psi), the DoD oil pressure relief valve is stuck in the
closed position.
