HJ 60 engine overhaul
 

Hello
During a drive the engine suddenly sized. Oppening the engine shoved that the "injector chamber" had worked is way down into the cylinder. There is serve damage on the piston. So i have to replace this. And now my concern is that this suddenly blocking of the engine has damaged the parts further down in the engine. Has anyone of you expiriences of engine seizing?
advise sought!

tanx in advance
