I just did mine a month ago. It's a V6 and was not that tough at all. Most people complain about removivng the Y-pipe, mine came right off after I let it soak with good old liquid wrench for a couple of days. Of course since mine is a left Coast car it doesn't have nearly the corosion of the East Coast cars. Anyway, this is one job where the factory CD is worth following, you should get one if you don't have it. There's a sequence to the bolt tightening that needs to be followed. You won't be able to use a torque wrench on one bolt but that doesn't seem to cause anyone a problem. You also need to put some RTV in two small spots, where the engine cover on the serpentine belt side mates with the bottom of the block. That part is confusing until you see it, then it's obvious. Autozone has a nice Feltpro gasket for $34 that works great.
