Gus!! I am far from a DeLorean mechanic, but the green stuff leaking from the water pump housing is an easy fix. (A new water pump). As far as the blue smoke, it may be as simple as valve seals or perhaps worn rings, still not a disaster. Find out where the oil is leaking from, the old newspaper on the garage floor trick, maybe just gaskets. I'm a firm believer in milking old cars to the max before spending the big $$$$. Dennis M.
