You don't need to remove the crank pulley to do the timing belt.

however to lock a motor theres a trick i use
cut a peice of rope 15 inches
remove a spark plug
push the rope inside the cilinder then go loosen the nut
DONT DO THIS WITHOUT A BELT ON!!!

If you absolutely need to remove the nut, there may be better ways, but this worked for me.
I had to remove the radiator to gain more clearance and had a bar welded to the socket for more leverage. I jambed the flywheel with a screwdriver so the car wouldn't move, then I made sure when I bumped the engine, the bar would hit on something solid to loosen the nut. BUT this is not necessary for a timing belt replacement.

The seals are leaking so i wanted to replace them while i was in there. I will need to remove the pulley right? Thanks for the replies. I dont know for sure that the crank seal is leaking as I havent pulled the cover yet but i put some dye in the oil and will be checking it out with the blacklite/glasses kit that my friend has. So far i can see that the oil pan gasket is leaking for sure...hence my other posting about the bolts.
