What to Do When Engine Oil Pressure Is Too Low?

[LeviFitz]

The solutions for low engine oil pressure are: 1. Check the oil pressure gauge and sensor, replace them if they are malfunctioning; 2. Check if the oil viscosity is normal, replace it with oil of appropriate viscosity if not; 3. Inspect and adjust the pressure relief valve on an oil pump test bench to restore normal oil pressure; 4. Clean the oil pipes and passages, and maintain the filter; 5. If the crankshaft resistance is too high during engine rotation, perform a break-in. The causes of low oil pressure include: 1. Insufficient oil quantity; 2. Contaminants in the oil blocking the oil passages; 3. Oil being too thin; 4. Damaged sensor; 5. Insufficient spring tension or improper adjustment of the pressure relief valve; 6. Severe oil leakage in the lubrication system pipes; 7. Oil fine filter damage and leakage; 8. Excessive clearance in main bearings, connecting rod bearings, or camshaft bushings.
