put a new power steering pump in it, and probably a new rack, i would say your pump is shot if its leaking because its probably been run dry. for the oil pan find the leak and see if you can put some rtv around the leak, this would be a quick fix and most likely temporary, but by no means is your car past the point of no return you have a lot of life in your 3800 run it till it blows then put in the sc l67
