Yes, there's no question the camshaft is unusable. I had already resigned myself to a new chain job - might as well go all the way and change out the camshaft while I'm at it. If the camshaft sprocket is worn, I would have had to pull the camshaft anyway - could be a blessing in disguise.
I'm betting the PO never discovered the slipped cam tip and couldn't figure out why the timing was always off. Must have driven him absolutely nuts.
