piston damage on skirts.
just wonderin.
on 400+ cossie yb,
if pistons(+.5mm 4*4 mahles) were new, in a fresh bore, run in period 1000miles,
always warmed up and down,
engines never boiled up, nor run out of coolant,
oil always fresh 10/50 fully, on max mark, and good oil pressure.
why did the piston skirt and bore score?
piston had good compression and didn't let go b4 strip.
cheers danny

To tight fitting of pistons for this kind of power?
