Why does the vehicle show low oil pressure when wading through water?
1 Answers
Here are the reasons for low oil pressure in a car: 1. Insufficient oil quantity or low oil viscosity. 2. Poor performance of the oil pump. 3. The oil pump relief valve is too soft or improperly adjusted. 4. The oil filter is clogged, or the bypass valve spring of the oil filter is too soft. 5. There is oil leakage in the lubrication system pipeline or at various sealing points. 6. Excessive clearance in the crankshaft main bearings, connecting rod bearings, or camshaft bearings. 7. Failure of the oil pressure indicator light or pressure switch. 8. Damage to the cylinder head gasket, or cracks in the cylinder head or cylinder block causing coolant to leak into the oil pan.
