Oil leak and tapping sound

You may have bought a nightmare; not entirely sure. Certainly - should have a total vehicle evaluation, preferably before you take the plunge... But, since you're at this point - the reddish fluid leak is probably transmission fluid, leaking at a transmission fluid cooler line. Or the cooler itself. It will need to be inspected to see what will be needed to secure the leak. Could be a simple clamp, could be as complex as a cooler replacement. Tapping sound...really going to need to be heard by a qualified technician first hand.
