What Happens When an Engine Lacks Oil?
1 Answers
The effects of insufficient engine oil include: 1. Abnormal noises from the bearing and journal contact areas due to poor lubrication from low oil levels; 2. Elevated engine temperature; 3. Valve noise; 4. Knocking sounds; 5. Cylinder scoring; 6. Engine bearing seizure or crankshaft locking. The causes of engine oil deficiency are: 1. Aging valve seals where rubber loses elasticity, leading to poor sealing and oil leakage into the combustion chamber; 2. Cylinder liner wear or poor piston ring tension; 3. Turbocharger malfunction; 4. Excessive clearance between piston rings and cylinder walls, improper piston ring installation, or poor sealing; 5. Wear between the valve guide and valve stem; 6. Failure of the valve oil control ring; 7. Sticking of the crankcase ventilation valve.
