check oil filter, sometimes gasket from old filter is still on engine and when tou have 2 gaskets, (the old one and new one on new filter) it will hemmorage out oil pretty quick. next time check to see if gasket is on old filter when it is removed. I found that out after $30 worth of Mobil 1 poured out on my driveway.

Replace the drain valve. They leak all the time.

The drain valve is attached to the fuel filter with 4 screws with the star head. You can use a correct size van allen wrench to unscrew these screws (which is hard to do with little space) and put your new drain valve in. The new drain valves have huge O rings that work better than the seemingly non existent washers that come from the factory. You will first need to take out your fuel filters and drain the filter body because when you take the water drain valve off, all the diesel will come out any way. This is a good time to take apart your whole fuel filter and clean it out good. An air compressor works great. Be careful with the plug in fuel heating element if you do take the plate off that it just under the filter (two allen screws). You can unplug it and clean the bottom of your filter housing so your water drain does not plug up with the stuff on the bottom of the filter housing.

it sounds like your water seperator valve is leaking ..it is the valve on the back of the filter bowl .it is attached with 4 screws .and has a tube that drains on the right front of the motor..it can be replaced in a matter of minutes and costs about 50 dollars..
