My buddies 07 LBZ started skipping and running rough, he pulled a code for a misfire thought it needed an injector, while he had the injector out we decided to look in the hole with a boroscope, yep piston broken!!

Would it be possible to replace the pistons without pulling the entire engine out? I don't think so but just wondering. If it wasn't so expensive it would be nice to be able to just put pistons in and forget about it before it even happens.
