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.
Why does cylinder head clamp affect piston clearance?
Bore distortion due to cylinder head fastener clamping load also influences final piston clearance figures. Depending on the engine and the construction of the block, it is also possible for other fasteners to distort the bore. These might include motor mounts, pumps, bracketry and so on.
What happens when the piston rings get worn out?
The engine inside of your vehicle contains a series of rings that are called piston rings. These rings help regulate the oil pressure and the amount of oil consumed by the engine. If the piston rings were to get damaged or worn out, then you will have all kinds of problems happening with your engine.
How does cooling affect piston to wall clearance?
The cooling style of an engine affects piston-to-wall clearace. Because air-cooled engines are at the mercy of ambient air temperature and flow over the engine’s cooling fins (shown), they see a wider variety of operating temperatures and need additional clearance.
What causes the piston to ride against the cylinder wall?
If the ring end gap passes through a port, which could hook the ring when it passes by the opening, something is probably installed incorrectly. A piston ring locator pin is typically in a position where, when the piston is correctly installed on the connecting rod, the ring will ride against the cylinder wall through full crankshaft rotation.
