You're probably correct CoyPatton. Again, I can't picture the size of the nut in relation to the gap available to fit through and roll around in. You would certainly know better than I. The scope is for sure the safest and best route to go. Hadn't considered that.
I have looked and can稚 see a thing. Bore scopes aren稚 too expensive, so I may add to my growing tool set.
Sixdogs, yes I did turn the cam. I moved it thinking I could continue checking the valves. When I felt a little tension I stopped, reversed a little and resumed probing with a magnet.
