Can't you fish it up with a small wire through the spark plug hole? You can look in there with a bore scope. I have the Pro Vision 100 which is .4" diameter and I have looked into cyloinders with it. It is about 140 on Ebay. This one is only 1/4" and going pretty cheap

I also bought a video one at Harbor Freight for 80 but I think it is a little bigger diameter like .45" or .50" so it won't fit (even though they claim it will...) But I got that one for looking into walls not engines...

Don't take it apart, you can do it!!
