Slowly working on my L29 engine and notice that the pistons all have what appears to be either scuffing or possibly burning around the upper edge of the piston, above the top ring. Has anyone else noticed this on their rebuilds and if so what do you think was the cause?

Most likely piston to tight against the cyl wall thus overheating and gauling itself on the cyl wall. Randy

On most all engines, the area above the top piston ring gets carboned up , especially as the engine wears and burns more oil. I call it normal.
My 2 cents

Troy,
Shelf wear usually found on the top of the piston. but thanks for the input.

So,
re-usable or buy replacements?

The skirts show slight wear, nothing unusual, just the issue above the top ring.

If it all measures out then there is nothing wrong with it, but the cylinder is a different story, if it is worn to much for this piston you will need to bore and sleeve the cylinder back to the correct size for this piston.
