TTBadDog,
Had the same thing happen to me once. There is a washer between the pan bolt and the pan (though I beleive it was brass) and forgot to reinstall the washer when I bolted everything up after an oil change. It started to leak. I went to the local hardware and purchased a rubber washer (OK'd for contact with oil) and installed. No leaks in over three years.
Hope this helps....,

 

Get a fumoto drain valve from dieselsite. You install it once and never have to loosen it again, just open the valve.

 

ReefBlue,
What about the little magnet on the tip of the OEM plug that helps collect residual metal block shavings floating around in the oil? Does this valve you speak of have something similar?

 

Get the Fumoto. I think it's brass, therefore no magnet . If you want a magnet, why not one on the filter, remove & re-install w ea filter change. Or get bypass filtration & no more worries.

 

If it continues to leak, you can get oversized drain plugs - 1 over, 2 over at Advance Auto Parts. I had to get 1 for my Fedex Ground truck (same motor 7.3L). I believe they are tapered too so you just get them started and they will recut threads as close to existing as they can be.

 

I picked up an assortment of copper washers, one of them should to the trick. Changing oil in the morning if I get the boat carb rebuilt in time.

 

Got mine from Autozone. They were able to look up the size. I got a couple of them for a few bucks.

 

Same problem with mine....it drips a good amount of oil lol


Im probably just going to get a rubber washer or pick up a new bolt from autozone ( im sure they can look it up )....then ill have to go borrow my buddies pressure washer to clean my driveway
