Do i need to split the case?

[Please help]

Okay so I got a 2012 rmk pro 800. The top end blew, one piston is fine the other one is beyond toast. So I'm getting refurbished cylinder and new head and pistons. My question is I found the on the crank case and wanted to get an opinion whether I should split the case for further inspection or just slap on a new top and send it. Look at pic for reference. But here's what happend. Top end lost all compression on one side and limped it to the truck about 5.5k rpm on one cylinder about 15miles. Got home then saw that the top end was toatally screwed. The pic shows the crank case missing a chunk but the crank spins fine. No sigs of any scratches or no sounds of anything inside the case. No play in rod bearings. Either the top end ate it. Or it was from a previous blow up. Should I tear into It In search of some metal, my thought is that if there was anything that significant it would've seized during my 15mile ride home. Powercaleves look fine. And exhaust looks fine. Idk where that peice went. Reeds on that side are missing a few chunks but replacing those also. What r your thoughts.

i would tear that one down and inspect every thing and replace the seals , also check the injectors

 

[Please help]

I checked injectors manually with 12v battery and fuel with 40psi in the line and they squirt fine. I assume that oil is fed separately so if a injector goes out it won't ruin a piston right?

Send it. But clean it up very well and reinspect. Then fog it(don't leave it dry). Leak test it when you get it back together to assure your seals are good.

I'd run it. But hey I'm just a random stranger on the internet.
