Another method:After you reattach the motor mount-
Jam a large screwdriver into the flywheel so that when you hold the screwdriver with your left hand, you can loosen the 18" extension on the crank nut with your right. Takes alittle control to hold the driver against the tranny housing, but it's pretty easy.
PB Blast (penetrating oil) the snot out of the crank bolt, repeately. You can also use some heat from a propane torch on the crank bolt.
My Civic's came off pretty easy this weekend, second belt and I used anti seize the first time. The first time though I was standing on a lug wrench trying to pop the bolt-then I learned of the PB Blast and heat.

Triple check the valve clearances, you don't want to put everything back on and hear a worse ticking. Are they ticking loud now? I've only adjusted mine twice in 332,000 miles. They sound fine and the motor runs fine, so I leave them.
You are doing the water pump also right?
