What Causes No Cylinder Compression in an Engine?
1 Answers
Engine lacking cylinder compression is primarily caused by valve leakage, excessive clearance between pistons/piston rings and cylinder block, or cylinder gasket leakage. Below are detailed explanations. Valve leakage: Wear, burning, bending deformation of valves during operation will reduce valve sealing performance, leading to decreased cylinder compression. Excessive clearance: Overly large gaps between pistons, piston rings and cylinder block can also result in no cylinder compression. It's recommended to replace the complete piston assembly (four-piece set). Cylinder gasket leakage: Damaged cylinder gaskets during use will fail to provide proper sealing. Replacing with new cylinder gaskets can solve this issue.
