So I tore my engine down after failing a leak down test.. Piston #3 had a broken oil ring. And Piston #5 had a cracked oil ring AND ring lands...
These are images of each cylinder's bore, piston, and head. Still on the fence of what to do but I may just get a new piston to replace the cracked one, re-ring the culprits and give it a shot. My concern is actually the pitting on the top of piston #4. The bore walls seem to be smooth with no nicks.
Any engine builders out there with opinions on this?
