Can the Engine Still Run with Piston Slap?

[DelTheo]

Engine piston slap means the engine cannot run. The causes of engine piston slap are: 1. Excessive wear of the piston and cylinder, resulting in excessive clearance; 2. Incorrect piston installation direction or piston deformation; 3. Poor lubrication of the cylinder wall; 4. Bent or twisted connecting rod; 5. Clogged oil passages; 6. Severe carbon buildup in the combustion chamber; 7. Excessive fuel injection advance angle; 8. Excessively fast combustion speed of the combustible mixture, leading to excessively high pressure in the cylinder; 9. Overly thin cylinder gasket or excessive wear of the cylinder block top surface, increasing the compression ratio of the diesel engine. The effects of engine piston slap are: 1. Loud noise; 2. Increased engine compression ratio, making combustion prone to knocking; 3. Causing piston cracking and cylinder head deformation; 4. Causing connecting rod bending deformation; 5. Damaging the cylinder head.
