Hi, I recently purchased a 2000 mustang 3.8 base which has 177K miles on it. The car overall is in good shape with a new alternator, waterpump, compressor, belt, tires, etc....But I noticed a small oil leak behind the engine. What could it be? It's quite a sizeable puddle whenever I turn the engine off. It's a manual transmission so I guess it would be easy to get to sort of. Anyone have any ideas on how I can test or check the rear seal without taking out the transmission?

There are no specific tests... you'll just have to look around. If the leak is dripping from between the bell and block, it's quite likely to be the rear main. Look at the sides and top of the bellhousing/block to make sure it isn't dripping from above from something like a valve cover or oil plug on the heads.
If the leak isn't excessive (like a quart in less than 1,000 miles), it might be worth waiting to replace the seal until you have another good excuse to pull the transmission... like clutch replacement.
