Scuffed Piston/Bore? - 05/17/18 10:33 PM
Inspecting an engine I bought.New Mega block 4.32 bore Ross pistons
.0055/.006 skirt clearance.
Engine has been sitting probably 10 years. Turns freely.
Anyway.pulled piston to check clearances and found this:
Pan is squeeky clean. Bore measures good all the way down,no burr at the bottom,wrist pin free.
Has about 1,000 street miles,low compression small hyd.cam.
It looks like either tight at bottom,is not.
Burr on edge,,no
Tight wrist pin,no.
