How does a piston get damaged?
A damaged piston can be a result of:incorrectpiston (too small for the cylinder),excessive rocking of the piston, insufficient compression, fuel flood, bent connecting rod, excessive clearance at the conrod bearing, uneven or pitted cylinder walls, lack of lubrication.
What is the likelihood of damage to an engine valve and pistons?
If your engine is an interference type which means the valves are so close to the tops of the pistons. If the time belt/chain breaks there is an extreme likelihood that the valves and pistons will collide causing major engine damage.
What happens if your crankshaft is not right?
The speed and position of your crankshaft need to be just right if your engine is going to start properly. If your engine control unit cannot receive accurate information about the crankshaft, then you will have trouble starting your vehicle. In some cases, you won’t be able to start the car at all.
What are the symptoms of a bad crankshaft position sensor?
Upon scanning for trouble codes with an OBD2 scanner, you may see crankshaft position sensor related codes such as P0335 or P0340. If you are experiencing any of these other symptoms in addition to the check engine light, then that increases the likelihood that the crankshaft position sensor is to blame.
What happens when the crankcase of an engine is raised?
The rapid pressure rise within the crankcase can cause the engine structure to be blown apart, causing physical damage, and the resultant flame travelling across the engine room space causing personnel injury. This pressure rise is limited by the statutory use of relief doors fitted to the crankcase.
What happens when you have two stroke piston failure?
Piston Failures/Causes Two Stroke Piston Diagnosis The process of examining a used piston can tell a mechanic helpful information on the condition of an engine. When an engine failure occurs, the piston is likely to take the brunt of the damage. A careful examination of the piston can help a mechanic trace the source of a mechanical or tuning

What kind of damage is caused by a broken piston?
Further damage in the ring and skirt panel Ring land fractures 36 Material washout in the ring zone 50 (ring fracture) Piston damage caused by broken 55 piston pin circlips Asymmetric piston wear pattern 84 (increased oil consumption) Radial impact points on the piston 63 top land Oil-consumption relevant damage
Is it rare for a piston to fail again?
It is not at all a rare occurrence for repairs to be carried out and then for the same damage to occur again and the same components to fail again because, although the damaged parts were replaced, nothing was done to eliminate the cause of the problem. For this reason a certain amount of “detective work” is always needed to track down the fault.
