Thanks guys!
I know everyone loves a good tear down, so here's what I found so far. One rocker face is worn out bad with a divot in it. The camshaft has locking pins in both ends of the camshaft to stop it from moving. Well they were both missing and you can see in the one pic where the camshaft was moving and the sprocket bolts where wearing a groove in the housing. That's the noise I was hearing. The piston and cylinder bore looks good so a good hone job and a new set of rings should be sufficient. I think the oil usage and smoke either came from bad valve seals or valve guides. I'll dig a little deeper when I get more time.
