My oil pan drain plug on my 2000 Jeep XJ with the 4.0 is stripped and just spins. It’s not leaking. How can I get the plug out and can the hole be fixed or do I need a new oil pan as some people are telling me?
 
I don't know of a way to get it out without making the existing pan worse off.....I really think a new pan is the best solution.
 
Getting it out is going to be a big issue. Somehow prying or pulling on the plug while you turn it with a wrench is the only way. BTW, oil pan drain plug torque is around 15 foot pounds. This happens when its way over torqued several times or, as one of my students did, half inch impact in tighten mode.
Another option is removing the pan, cutting the head off and smacking it to the inside. At that point it easier to replace the pan.

They make self taping drain plugs for stripped threads. I'm my experience they only last a short time. I would definitely get a new pan. I say this because you said the plug just spins.

There's another alternative if you have enough thread left. When I got my cruiser it was 20 years old. The drain threads were worn but not leaking. I installed a drain valve to see how it would work out. We have these at work so I've seen them for years. My pan is high enough that I don't worry about breaking it off. If it wasn't, I would have a skid plate protecting it anyway.
The only down side is it takes forever to drain. I just open the valve and go do other maintenance.

Thank you, I’ll probably go with a new pan. Now to find someone to change the pan out. Unfortunately I can’t do it due to my disability.

My daughter had this problem with a newish VW. My first question to her was- who changes your oil? Jiffy lube- lesson learned.

That company put an air chisel through my sisters oil pan while changing the oil. Mercedes diesel. No oil pan available in the world. I found one at an ebay junk yard.

Oil changes have been done at 2 jeep dealerships. It was one of them that stripped the drain plug.

Lisle and Super Crazy Tools make specific oil drain plug tap kits. Just hire someone to do it. Run a quart of oil through engine and out open hole before you close up the newly tapped hole to remove shavings. This is so common of a repair that to not try it before full pan removal would be to risk throwing big money away.

I will check them out. Thank you
 
Even if you were able to remove the plug, it is very probable that the threads in the pan are toast. Tapping new threads is an option, but make sure it is tapped to fit a new plug and as mentioned by another commenter don't forget to pour some oil through it to flush the shavings. If you have a leaky rear main seal which is common on XJ's, it may be a good opportunity to just get a new pan and replace the seal.

I wouldn’t trust a jeep dealership any more than I’d trust Jiffy lube. You need to find a mechanic and proceed to develope a positive business relationship with them. Or- DIY.

...and, the problem with tapping a new thread is that there's less metal in the opening, and hence more possibility of the failure of the connection. New pan is the best solution I think.

Jeep was bought as a project. Unfortunately I got hurt and can’t do much after 2 back surgeries. Looking for a mechanic.
 
Push/drive a chisel/screwdriver/prying implement between the head and the pan, back the plug out with a wrench, using pressure from the pry. Use one of the commercially available repair kits, or pick your own plug , tap to the correct pitch.

Pack the flutes on the tap with grease to catch the chips.
