Well, went and looked and brought it home. It cranked over and sounded like it only had compression on a cylinder or 2. Didn't see any movement on rocker arms through the oil fill hole. Couldn't wait to look and see what the deal was so I ripped it apart. Idler gear that drives cam and injector pump is toast. The cam gear looks a little tough too. Also has 8 bent push rods. Pistons look fine. Valves don't look bent, but will have check them out.
