started up went thru like two firing orders and now will barely turn over bad main bearing? [align=right][/align]

 

Bad starter and/or battery

 

both new yanked the motor bad bearing

 

alright here is what i found at first glance alluminum everywhere

there are two pistons that have a tiny piece missin off the skirt and a crack what the **** caused this

 

Who put the engine toghether? Was the engine spun by hand frst to see if it could turn easily?
Possibilities:
A lot of coolant or oil in combustion chamber, causing hydrolock
Pistons hitting the heads
Valves hitting pistons
Bad ring gap
Really bad ignition timing
Foreign stuff inside engine.

 

i was to lazy to build so bought one from the advertiser that was just rebuilt ( half *** Obviously)
motor turned fine by hand

why is there just lil pieces off the bottom of the skirt and not cracks or anything at top

 

well ripped the whole thing down spun a rod bearing on 8 and it looks like maybe the cam lobe knocked the piece of the two pistons
what did this guy do to this thing
