What causes the engine oil light to occasionally turn on and off?
1 Answers
The reasons why the engine oil light occasionally turns on and off: 1. Insufficient engine oil level, which reduces the oil pump's output or causes it to fail to pump oil due to air intake, leading to a drop in oil pressure; 2. Overheating of the engine, which can thin the oil, causing it to leak excessively through the gaps and resulting in decreased oil pressure; 3. Damage to oil pump components or excessive gaps due to wear and tear or assembly issues, which can cause the oil pump to fail to pump oil or pump insufficient oil; 4. Improper clearance between the crankshaft and the bearings (big or small), where excessive tightness can increase oil pressure and excessive looseness can decrease oil pressure.
