Have a nice long straightedge on hand to block the lifters in the cam tower when you remove it, otherwise you get a shower of lifters on your shop floor. Many recommend tapping the cam tower bolt heads to "wake them up" before trying to remove them - a good policy, given that if you strip one of the internal bolts you're in a world of hurt - you'll need a very long 6mm hex tool to get them out. The gasket goes on dry, and a little blue Loctite on the outside bolts will prevent them from backing out and allowing the gasket to leak again. This topic has been covered a lot, as it seems an endemic problem - I've done my 944's cam tower twice in 10 years. Of course, there's the whole timing belt tensioning job to do as well, but that's been covered thoroughly as well. This is a pretty easy job if you're careful, and a good relaxing couple of afternoons. It's also a good time to replace any lifters that feel soft or are making a racket.

Have fun!
