Oil Pan drain hole stripped (my fix)

    I know the best way to repair these pans is to pull it and weld a nut
    on the inside. What in the world was the manufacturer thinking when
    they didn't? As an engineer myself, that kind of poor engineering
    really chaps me.

    Anyway, I tried many things to no avail. Yesterday I installed a
    rubber O-ring that just fit around a x1 oversize plug, and I was able
    to get enough torque. Not a drop is leaking now.

    and why would you weld a nut on the inside???? It would block some
    drain oil. we have always put it on the outside. KB

    i have an oil pan on my car that is 39 years old and hasn't stripped
    yet. it's just a matter of knowing how tight is tight enough.

    And replacing the crush washer helps too... that way when you get it tight
    enough, it is the washer crushing and not treads pulling that's going to
    keep everything sealed.
    I personally use a torque wrench because it's not always easy to know tight
    enough.

    Because that's the way most oil pan's that were engineered correctly
    were done...unless the metal was think enough.
    I don't see where a nut that's 1/16" is really gonna make a lot of
    difference on the oil draining.

    Exactly. I've never stripped one myself. Basically the same type of
    mechanic that over-torques lug nuts, over torques drain plugs. 25
    ft/lbs is plenty of torque on that bolt.
