So im 21 years old and I'm attempting my first rebuild on my 16 axis 800. Well once I tore into it, looking into the reed port on the PTO side I noticed this chip at the end. Was just hoping it would be a top end but looks like I've got bigger issues. Wondering if its salvageable or if I'm SOL and need a new crank case. Also threw in a pic of my shot piston and wonder if the jug looks fine or would that need work too. Any advice helps as I'm pretty green to engine rebuilds.
