Contamination / High speed / Oil temperature
Severe damage in cylinder bore at
the pistons turning point.
Reason is to high speed, the piston
is thrown out in the pherferie and
breaks through the protecting oil
film.
High speed wear at the outher
pherferie on the cylinder barrel. The
protecting oil film can't withstand the
high speed.
There are also cavitation marks on
the cylinder barrel.
From the same cylinder barrel there
are severe cavitation marks in the
