[QUOTE="Tazza, post: 52475, member: 82"] If its on top of the chain case cover it could be the pintle arm seals, the fluid drips down under the pump and falls off at the lowest point on to your cover. It may be hard to see, but the centering plate on the right, look at the metal blocks that the steering levers join to, there will be a small space between them and the pump, does it look wet around the shaft/seal? one for left one for right. Access to see is not at all fun, but hopefully you can get in there to see. The only other points that can leak are the main seals between pump segments, but if the pump was not fiddled with, they should not go. Another possibility is the main seal from the rear of the pump. Put your hand through the blower housing and feel around the U-joint, is it wet here? or even the rear of the pump, just under the back? There is a seal that seals a shaft from the engine, they can and do go bad. They aren't all that hard to replace if it is indeed it. Sorry to give you more things to look for, hopefully one will be the issue, and not too hard to fix! [/QUOTE]
