When your oil pressure relief valve is stuck, you might notice the following symptoms:

1. Fluctuating oil pressure gauge
2. Unusual engine noises, such as knocking or ticking
3. Poor engine performance, including stalling or hesitation
4. Oil leaks around the valve area
5. Check engine light or low oil pressure warning light

Potential Causes of a Stuck Valve

There are several reasons why an oil pressure relief valve might become stuck, including:

1. Contaminated oil or debris buildup
2. Corrosion or rust
3. Mechanical wear and tear
4. Manufacturing defects or poor-quality components
