camshaft oil seal plus belt tracking

I'd check the position of the crank pulley and the condition of the rubber
"damper" part of it.  This being out of "alignment" is the only thing I can
think of which will caused the belt to track that way.

Thanks, Tony.  Got it in with that tool and a longer bolt.  Not good at 
hammering straight, so using the bolt to pull it in works more 
comfortably for me.

Now I have a tracking problem with the belt:  It wants to run to the 
outside of the camshaft and water pump pulleys so it sticks out maybe 
3-3.5mm as measured from the camshaft pulley outside surface.  I can 
line it up and wind the engine over a half dozen times with a wrench and 
it works its way out about that far.  I tried putting on the plastic 
upper cover, to see if it would rub that way, and it DOES rub, but the 
cover pushes it back into alignment on the  camshaft pulley.

It's a Conti belt.   Is this just wear-in stuff?  Will it stretch and 
straighten out eventually?  Belt has been wound up in its original box 
for a couple years.
