Hoooo boy this is not what I expected, but I'm glad I checked. I'll check the other side next.

To be honest I don't know if this is buildup or melting/welding. The really interesting one has a scoop in it where the valve was hitting, so I'm assuming buildup.

The white piston had a cylinder completely full of ash.
