OIL and WATER !!

The up side is once the cover's off, it's a very easy fix. On your leak, you need to figure out what's leaking. If its the filter, replace it. If it's the plate, get the gaskets and replace them. If it's the pan, you could try snugging the biolts but that is temperary and if it's a gasket leaking, you need to drop the steering, then the pan, and replace the gasket. Not much else you can really do...
