Anyone have experience replacing the valve cover gasket on a Volvo, or general experience with engine seals in cars?

I own a 1994 940 GLE Wagon with 175,000 miles on the odometer. I don't drive the car much during the school year, so I just recently discovered an oil leak that substantially drained the reservoir since I last changed the oil two months ago. I think I lost about 3 quarts of oil, and there is quite a mess running down one side of the engine. After much consternation, cursing, oil cleanup, and test laps around the dorms, I've determined the source of the leak to be in the joint between the valve cover gasket and the cylinder head. The car is running perfectly, the engine oil is untainted, no oil in the coolant, no white exhaust smoke, nothing is running hot, so no signs of anything Very Bad like a blown head gasket. I’m just slowly re-enacting the Exxon Valdez spill all over town. Phew. Simple repair, $20 shipped for a new valve cover gasket, I just need a socket set to pop off 10 bolts, and everything is right on top of the engine where I can easily reach. I can throw some sealant on the new gasket when I install it for maximum longevity. At least, things seem that simple. I've replaced belts, hoses, and electrical components before, but have never needed to work on the engine directly. Advice and anecdotes from anyone who has experience with this kind of work would be welcome. Maybe the repair is actually as simple as it seems!
Bonus Question: I refilled the oil with the special high mileage variety, just for the hell of it. Does this stuff actually help preserve seals and does it have any additional benefit? Is buying this stuff at over twice the price of regular oil more cost effective than replacing seals (which seem to be very cheap)?

Sorry, couldn't get the direct link to work for some reason.
I think I might need to replace the oil cap seal as well; it looks like oil has also been coming out of the top.
