  • Milodon Oil Pan Improvements

    I found a great deal, on a near new Milodon 460 Jet Boat oil pan. So after all I have read, and heard about, regarding long, high rpm, runs having issues (with this pan) I decided to copy the improvements, Armondo's Jet Boat Pan incorporates, on this one.
    A big thanks to JohnF, who took a few pictures of his new Armondo Pan for me. The additions this pan needed, is 2 sets of gates (instead of 1 gate, that only went 3/4 across the rear) to keep the oil near the pickup. A full windage tray (instead of a narrow tray) and the addition of 4 oil scrapers, to help keep the oil off the crank. I made a copy of Armondo's pick-up tube and screen as well.

    Here is what a stock Milodon Jet Boat Pan looks like.





    I made another panel with 2 gates in it, and made a small section, to fully enclose the original rear gates in the pan.



    Then I copied the windage tray, Armondo uses in his oil pan.



    I made sure, and test fit the pick-up. It has to clear the windage tray, and still drop in, to be 3/8" to 1/2" from the bottom.

    then I test fit the pan with the new windage tray.



    Next was to weld in the crank scrapers. Just need to finish welding the ones on the windage tray,

        Finished up the crank wipers, on the windage tray. Test fit everything on the block. Next up, oil return mods to the early 460 block.







        Kind of wondering, what to paint it with, or if I should have it zinc coated, or something.

              I thought paint would hold heat.?
              I know when it comes to the cylinder on my 2 stroke, it was better to polish it, then paint it. (but i guess polishing the pan isn't the question. lol)

                  we found back in the early 80's off road racing VW's. Painting the engine cases black,. made a 20 degree drop in oil temperature! that was in the Desert.

                      I was thinking about having it powdercoated. Maybe that dull aluminum color or something.
