I've "broken" cars that come in for a dyno (back in the day). I'd let the customer know, hey the car blew up, be up-front and as honest as possible. My gut feeling is there is no sticking ring, one cylinder is bad and it is intermittent, keep running the motor and the engine will lock up and then toss the rod out the block. Any good shop would have a bore scope and look for the tell tail wear marks of a broken ring land / seized ring. Remmember it is not the rod bolt breaking and the rod flying out, it is the piston locking into the bore that fails the rod bolt then the rod flies through the block.
