 If the outside edge of the belt is showing heavy wear be SURE to check
the pump shaft for wobble.  Just grab the big pulley and wiggle it once the
timing belt is off.  It's a bushing instead of a bearing and they wear egg
shaped, toward the direction of pull.  About toward the tensioner.

  The pointer is on the engine side of the hole, down at the bottom of the
threads.  It helps to wipe it clean.  :)

  The plug is actually plastic and the reason it's there is only to plug the
hole the special tool goes into, to remove the big plug so that you can
see the pointer and mark.  :)  Without a special tool you can make one
out of a bolt with the appropriate sized head, or just grab it with a pair
of channel locks, from outside to near edge of hole, and turn it out bit
by bit.

  With the cam lobes point upward and the rest, it sounds like you'll see
the "o" with the little "v" above it when you pull the plug.  :)

  I have a cam plate but only because I got a good deal on it.  :)  I just
eyeball the slot to the top of the head.  The plate always just slides
right in after I eyeball it.  :)

  When you know where everything goes it's not a problem if the crank
turns a little.  You don't have to pull the big bolt on the crank, just the
4, 6mm allen head bolts.  The pulley is indexed on a little bump on the
crank gear and a dent in the pulley.
