Just make sure you use the right amount of sealant and torque the bolts down in the right order and follow the curing instructions on what you have.

I put a nice thin bead down on the cover like the maintenance manual said to do. Cured over 24 hours, added oil, coolant, and ran it. Currently have just under 200 miles on it (it's like 100 miles to drive to and from work) and I have not seen any leaks yet besides a mystery coolant leak that I've yet to find the source. I believe the coolant leak is from my radiator as the previous owner was in a rear end/headend 3 car pileup and the condenser and radiator have a bow to it that I only just now saw when doing this project.
As for what some people have said in this thread, for anyone ever attempting this at home, this is one of the biggest projects I've taken on next to pulling and rebuilding the engine in my first car. Take every precaution, go slow, get new packings and seals, and read the service manual. Expect your car to be out of service for 3 days, 4 days max. Also it cost me around $300 for the parts, fluids, and tools needed.
