Just for grins, I'd want to take a peek at the top of the piston, but I'd be satisfied with looking with a bore scope and not going through the work of pulling intake and head. There are many, hand held/w their own screen, for under $100. Also, there are many scopes that work from and app through a smart phone, using the phone's screen. I've seen these for under $20 and the one I have works just fine.
