Before removing parts, go to the $0.99 store (or similar) and buy 4-5 cans of engine degreaser, and 5 cans of brake spray cleaner . Spray degreaser all over the engine and let soak for about 30 min. Then wash away degreaser with brake spray.
All cars with lots of miles and time on them will leak.
After repairs are made, they won't leak for a very long time.

The cam seals leak, and are not too hard to change. Check t-belt fot wear and oil contamination.
Front crank seal leak. Power steering hoses and pump seal leak. Parts Plus has quality hose for about $100 (toyota is $323).
VC gaskets leak. Distributor/cam sensor O ring, and internal seal leak.
Check in the FAQs section for info on these repairs.
Head gaskets seldom leak alot of oil. USUALLY just seepage.
