What Causes the Abnormal Noise When Accelerating in Honda Lingpai?

[VonPaul]

Honda Lingpai produces abnormal noise during acceleration, and the causes of the noise are as follows: 1. Loose connecting rod bearings, melted bearing shells, or incorrect size causing rotation. 2. Loose crankshaft bearings or melted bearing shells. 3. Broken piston pin. 4. Broken crankshaft. It should be noted that if the noise comes from inside the engine, it is often impossible to solve it on your own, and it is best to send it to a repair shop. Below are the causes of abnormal noise at other times: 1. The noise only exists during idle or low-speed operation. The causes include excessive clearance between the piston and cylinder wall; overly tight piston pin assembly or connecting rod bearing assembly; excessive clearance between the tappet and its guide hole; worn camshaft profile; sometimes, a loose starter clutch causing the pulley to make noise (especially noticeable when the speed changes). 2. The noise becomes chaotic at a certain speed, and short noises are emitted successively during rapid deceleration. The causes include cracked camshaft timing gear or loose fixing nut; broken crankshaft; loose piston pin bushing; excessive axial clearance of the camshaft or loose bushing.
