So one day you walk out move the car back run inside to get something and see an oil drop on the ground what could it be. A real comment sight to see is the vacuum pump leak. The vacuum pump for the brake booster is on the transaxle side. The seals go bad and there is no reseal kit. If you happen to have a manual tranaxle this is no big deal but on the auto transaxle side there is a nice short cut to get the pump out without taking the trans out.
Fist step is to get a few tools, sockets, xyz 12 point and a few ratchets.
Next pull the battery and battery tray out, then remove holding bracket on starter 13mm hexnut.
Then get under the car and take the torque converter nuts out, this will allow fow some free play. After that take the 16mm bolts for the trans-engine bolts and loosen them. Do not remove only loosen. Once all are loose disconnect the pendulam mount from the engine.
Get a block of wood and a floor jack. Push the center where the engine and trans meet up. If you did not loosen the bolts for the trans enough you can loosen a little more but remember do not remove. This will allow the vacuum pump to be removed.
