O-ring

The heart of the engine relies on the pistons fitting at precise tolerances, no little end movement, and the piston rings sealing correctly.
With luck all that will be required is a new set of standard piston rings and a few gaskets and fasteners to restore full power and a smoke free exhaust.
If, however, the wear and/or damage goes a little deeper, then this component and perhaps some of those listed below maybe required:
