Went to change teh oil on the "new to me' truck yesterday, and found that the drain plug was rounded off....wrench wont grab it...
so got out the trusty " one size fits all" vise-grips and locked'em down tight and tryed to remove the plug....bad idea.
no luck.. that thing is in there like it was welded, and now( thanks to my prowness with tools) is as round as a marble...

Any suggestions on getting the dern thing out????????

BTW anybody know the proper size, so I can find a replacement?

Wow! At this point you might try the vise grips and alittle heat. Not too much though, you'll cook the oil. Are you turning it the "right" way? Lefty loosy. If that don't work you'll have to drill it out. Can you remove the pan?

Heat it up and use a pipe wrench?

Get a new plug at a cummins shop.

Not being from Nebraska, "lefty loosey-rightey tightey" is something I stopped saying in grade school.... Tho I have heard that is how they teach the NU football team to turn on the showers.......

Tryed heating it a little, but was worried about baking oil to the inside of the pan..

Didnt think of the monkey wrench..... gonna have to try that if no-one chimes in with a better idea...

Not bad lizzie.......................

Try a small 8" pipe wrench. Worked for me.

That's funny right there! I'm just surprise those big corn fed boys take showers! Don't worry Gieco, I'm still sad they lost!

Weld a nice large nut to it. That usually works for me on stuff like this...

Yep, your best bet would be to weld a large nut to it. Then get a new one from Cummins.

A lot of times, tapping with a small hammer will help loosen things like that. Tap it on the left side with a chisel might help also. Then try the pipe wrench. Hold a good bind on it and tap on the plug at the same time.

Yep, that would be my last choice but effective. I would drill out the center of the plug with something close to a 1/4 inch drill which would drain the oil if you go through making a mess. Then use the size Easyout that fits in the hole good with a tap handle and attempt to remove the stuborn plug. If that fails, weld on a large nut. The tap handle applies torque without side loading the easyout when using two hands. If the easyout breaks you will need to weld the big nut as they are too hard to drill using conventional methods. Good luck. Oh! By the way, be careful if you are going to weld. You don't want to arc strike the pan and put a hole in it.
Another method that has worked for me in the past is to grind a slot into what is remaining of the plug head and try using a drag link driver and a breaker bar. Apply torque while you or a friend is rapping on the breaker bar to help seat it into the slot with a light no mark hammer or mallet.

you could try to grind two flat spots of the sides of it so you could grab it with a wrench again.

Lock the vise grips on as tight as they go. Then some tap tap taps with a hammer. Usally works for me. If not the weld a nut or grind some flats sound like good options.

Okay, Mr. Meanie. Get 4 pounds of C4 and place it next to the oil pan. Insert blasting cap light fuse and stay VERY close to watch for leaks.




You do know it's a left hand thread right?

B12 + lit match = C4! Redneck math.

Geico266

or give it enough bite for a pipe wrench. Good idea.

Here's what I would do.

Take a drill and drill a hole in the drain plug.

Tap threads into the hole.

Buy a plug that will fit the threads.


Now you have a brand new drain plug with half the fuss.
