I am tearing apart a 08 summit 800 engine for a new top end. There is a little chunk missing from the top of the piston and i am wondering if there is any way the shrapnel could've entered the crank case. I know that if the piston skirt blows apart it needs to be cleaned out, but this seems more specific to the top end. Do I need take the engine all the way apart and clean the bottom out or can i get away with just a top end rebuild. Honestly i should probably get down in there and re-grease the crank bearings and replace the seals because its a new sled to me and has 3000 miles on it but i want to know if top end only is even an option with this kind of damage.
Also the piston walls were scratched up. I'm assuming they need to be replaced but any opinions there would be appreciated as well.
