Default LS6 balancer broken. Is my engine FU#@*%???

Hello everyone. Brand new to this forum so forgive me if this is the wrong section. My bro has a CTS-V and it's been hit in the front...HARD and the balancer completely snapped off from the hit. A few other components(alternator) are broken also. My question... is there a chance that any of the internal components may have been damaged? I'm mostly concerned about the crankshaft since the balancer was broken. The cover for the front of the engine has a little crack in it also(right behind the balancer). I"ll try to post some pics. Thank You very much

You are correct. There is a very good chance your bros crank is fucked.

Thanks ShortChevy. You think I'll be fine by changing the crank? Or should the piston and rods be changed also?

from what ive seen a good hard hit like that usually wipes out the thrust bearing , a friends 6.0 truck motor didnt have a broken balancer that he knows of and it ate the bearing up pretty quick

also the oil pump tends to get damaged , since its right behind the cover , most places on ebay , tend to show the motors running and give oil pressure readings for those reasons

but as bad as that looks , id put a short block in it and not mess with that motor

I would pull the crank, have it checked, replace the thrust bearing and oil pump, timing set and cover just for peace of mind. YMMV

Thanks guys, appreciate it very much. I've never done a rebuild so maybe this will be my first. I guess I'll take the oil pan out and check the crank. We'll see how it goes from there. Again, thanks for your input. A lot more questions to come.
