Stuck and stripped oil drain plug?

Do you mean the plug's real tight in there, and the head of it's rounded off so you can't get it out ? 

Have you tried a six sided socket ?

If that doesn't work they I'd use a small blunt cold chisel or engineers punch to tap the head of the drain bung around a tiny bit, a little on the left, then a little on the right, then a little on the left again, then try the six sided socket again. Put the socket on then give it a tap with a hammer to make sure it's right on and to loosen the grip of the drain bung. Then you need to apply as much pressure as the grip of the socket will allow, and hold it there till the plug begins to move.

It you mean the drain plug is out but the threads are stripped in the case where it goes, you could ask at an auto shop and them will be able to get you a slightly oversized plug.

Thanx.  I've tried the socket, but haven't tried tapping the plug.  I'm gonna give that a shot .

If the bung has a flange, try tapping that around with a small slightly blunt cold chisel, or a nice new engineers punch with a sharp (90 degree) edge to it's end. If there's no flange then try tapping on the flats, near the ridge the socket usually touches. If you use a chisel there, you can sometimes raise a little metal on a couple of flats and it's enough, with the nudge from tapping, to allow the six sided socket to grip. Tapping the plug on it's end might also loosen it a little, and at the same time splay the edges of the hex, allowing a little more grip for the socket. Don't hit too hard anywhere, or use too sharper chisel.. The idea is to raise a little metal as much as move the plug.

You can get  stripped nut and bolt remover sets.  They  have a  reverse twist so  when  you drive the one  that  has the best bite onto the bolt head or nut they bite into it.  When  you  turn them  with your ratchet wrench the bite in deeper with the torque to remove the nut / bolt.

Nut removers are the way to go!
