Nick in piston

[GavinT]

Whilst decarbonizing this piston I discovered two nicks in the valve recess. Does this render the piston unserviceable?. The piston is from a replacement engine that I have not seen or heard run. I checked the valves in the head that came with the engine and there is no evidence of piston valve contact. The scuff marks and scratches are also a mystery. I used a blue shop towel and carb cleaner to remove the carbon, so there not from me. Thanks.

It does look like something got caught between the piston and head at some point, but given the minor damage personally I would run the piston if all else was well. Any marks on the head to indicate if it happened with the head on or off?

The head looks fine. Nothing to indicate contact.

Smooth out the nicks, and it’ll be fine.
