There is no way to visually inspect either. Use an OEM Cummins unit, take it home with you and paint the heck out of it and mark your timing letters so that they are easy to find/read. Clearcoat with some automotive paint if you have the time. No paint, no warranty. The dealers/shops will not paint in most cases if you have them install.

I would also install new crankshaft and camshaft timing sensors, they are both the same part numbers.

Mine is already replaced just had a rebuild last year. I'm not sure if the crankshaft timing sensor was replaced or not but i know the crankshaft was.
