    Default drain plug leak

    I have a Milodon 10 qt jet pan that leaks at the drain plug. it came with a cheese O ring, that must have split at installition. anybody have this problem. or any ideas. the plug looks like a large (1"or so) anodised plug . maybe a AN plug? I'm thinking copper gasket, any ideas. thanks steve.

    I switched that plug out on my Milidon.
    If memory serves, it is a 20AN "O-Ring" fitting.



    I never had trouble with mine though.

    I put an right angle swivel adapter for oil drain hose.

    I would take the drain plug out, keep it, throw the 460 away, and put a new Chevy big block in over it!!!

    Default Drain plug leak

    Nylon washers work good for me, most factory cars/trucks use them, you can get them at Napa or Carquest.

    460 the "oring" with the "huge fitting" is pretty standard on thier pan design Its does not lend itself to being tightened to tight and tend to "pooch" out the oring and thus leak Maybe give thought to boring /drilling and tapping that plug thru the center and then sealing the big plug in the pan and removing the smaller plug instead !?? personally I like the extra large plug feature Tom

    I would simply hit a good hardware store and replace the o-ring.

    Take the old one with ya.

    I did the same thing...
    if you need a new o-ring simply take the drain plug down to a hardware store and fit it up. No need to over tighten just get your 90* fitting facing towards the rear.

    In any oil or gasoline application make sure you use a viton (flourocarbon) o-ring, neoprene (common at auto parts stores) will swell up when exposed to oil over time. And a decent durameter (hardness rating), 75 or higher works well. A bearing supply house is probably best source locally.

    can you tap the pan 3/8 pipe.. and put a 3/8 pipe male to -6 or -8 male 90 deg AN..and put a an cap on it ? or run an AN hose to rear of hull by the transom drain plug ? if you leave the hose long enough it will pass out the drain hole in the hull and you can drain the oil without having to scrub out the hull out with simple green ?
    something i have wondered and wanted to try out.
