Just sprung a pretty good oil leak from my oil pan. The best I can see, it looks to be at the drain plug. 2000 5.0. the only corrosion I can see on the pan is right around the drain plug. The plug never gets used. Trying to avoid pulling the motor in the middle of the season.Thinking about changing the plug gasket, clean the area as best I can, and lay on some marine tex around that whole area. Any better ideas or product to use?
