As many of you have read, I have been repairing an 86 that I bought with bent valves. Turns out that all 8 valves were bent. In taking it apart, I found no obvious signs of failure in either belt or any of the tensioners. The belts were all tensioned properly but the timing belt had somehow jumped time and cause catastrophic results. Once I put the freshly rebuilt head on, I decided to take a look at replacing the seals in the cam box. Going through the procedure for disassembly, I found this:





It appears as if the cam sprocket shifted on the cam itself and allowed the timing to become misaligned, thus causing valve and piston contact. I'm not sure at this point what I will have to replace. Maybe just the cam sprocket and woodruff key..maybe the entire camshaft. I'm having issues getting the woodruff key out and removing the sprocket. Any thoughts on this damage?
