Well, I finally started taking this thing apart to check out the damage, and unfortunately, it looks catastrophic (at least to my untrained eyes...). It looks like the intake cam at some point began to contact the walls of the head itself. And as you all know, metal-to-metal contact is NOT a good thing....My guess is that the oil was so sludged that it failed to penetrate that crease, which resulted in the two metals contacting at a high rpm, and thus melting parting of the head and scoring that cam
the cam damage
exhaust cam for comparison
So, is this head basically just a big paper weight now? Or is it machinable? My guess is that the cam is done....but then again, I really know nothing
