I've done this without removing the engine. I removed the bolts from the mounts, jacked up the engine, re-installed the bolts into the mounts and set the engine back down on the bolts. This left me enough room to get the pan off.

Its a pain doing it in the truck though.

If you can get a 1 piece gasket....much easier to install, is reusable, and almost surely won't leak.
