how many bolts are there to the timing cover?
If you use an air ratchet the bolts will come off the balancer with out it moving, if not, you are going to have to remove the starter and wedge a large pry bar in the teeth of the flywheel and this will hold it. It easier to use an air ratchet.
After pulling off the crankshaft pulley then do I need to pry off the balancer?
Last question - how can I tell if the timing cover is cracked or not? And will one from a wreck yard work?
