What would be the effect if the oil system pressure relief valve stuck in an open position?
Oil pump pressure relief valves can fail in either the open or closed position. This can cause damage to the engine oil filter and to the engine itself. A pressure relief valve that is stuck open can allow too much oil to bleed off. This results in a lack of oil pressure and catastrophic engine damage.
What causes a pressure relief valve to fail?
System is Over Maximum Pressure If your system is above pressure and your pressure relief valves have not released, this is likely a functional pressure relief valve failure. Contaminants, like dirt, lint, rust, sludge, or even the misalignment of the valve can cause the pressure relief valve to stick.
How do you open a closed pressure relief valve?
For most units, open the water pressure relief valve by simply lifting the valve up until the attached brass stem rises. When you do this, hot water will rush out of the pipe near the bottom of the water tank. Then, push the lever back down to close the valve and stop the water flow.

What happens when the oil pump relief valve fails?
This allows oil to flow back into the crankcase preventing excessive oil pressure. The spring tension of the relief valve determines the maximum oil pressure. Oil pump pressure relief valves can fail in either the open or closed position. This can cause damage to the engine oil filter and to the engine itself.
What happens when a pressure relief valve is stuck?
• A pressure relief valve that is stuck open can allow too much oil to bleed off. This results in a lack of oil pressure and catastrophic engine damage. • A valve stuck closed will result in excessive oil pressure. This can blow out the oil galley plugs in the engine block.
Why did I Lose Oil pressure on my Chevy 5.3L?
Hello – since you didn’t appear to be leaking oil in a significant way (busted oil line, hole in the pan), I suspect that the oil pressure relief valve may have been stuck in the “relief” position. Some of the early 5.3l engines had trouble with this – galling in the pressure relief valve bore.
