Broken Oil Drain Plug

WOW, Guys enough is enough!
Take the bickering to a PM!

Sorry dad...

Todays update: I used the chaser to clean the thread. Some more metal shavings came out. I put in the new plug in and tightened it up slowly and carefully to about 12 lb ft torque and then it started to spin again.

The threads in the pan are toast.

Considering the amount of thread you pulled out I'm not surprised.

You can try tapping with the same size bolt but different thread, but it's probably too far gone for that.
If you already have a tap that size it wouldn't hurt to try, if not I wouldn't bother.

After that your next step is either drill/tap the next size up or helicoil.
Next size up will require a different drain plug.
Either will work.

It should be pretty obvious which I prefer, but the choice is yours.

If you can't/don't want to do one of those you'll have to replace the pan.

Jamming a rubber plug in there is a temp solution IMO.
Just saying.

The threads in the pan are toast.

We agree!

Here is some alternative to the helical helicoil that has M12 outer threads and M8 x 1.25 internal threads that could be used.

I am not sure what threads your (new) plug has so this might not be the correct pitch for your plug.

Good luck with whatever method you choose to use (and there are other solutions out there)

That's probably too large for the bung.

There are also thin walled versions.

I saw one that had 1/2 OD threads

Seems like there are a lot of different versions of thread repair that can be selected from.

Yup.
Lots of ways to skin the cat.

I'll take "things uttered on prom night" for $200, Alex.

As mentioned, a Heli coil would be best for someone who is experienced with installing them, and at the risk of having to break out my pecker to measure it, I'd suggest an over size self taping drain plug for someone who doesn't have experience installing Heli coils.

You 'could' try putting 1 or 2 washers on the bolt then the rubber(sealing) washer and hope the threads tighten, maybe..
I'm pretty sure though you'll be pulling the pan off.....

Once the old screw was out this could have been easily and reliably fixed in 15 minutes by anyone that can operate a hand tap. No need ro remove or replace the pan and no special skills or knowledge required. Jiffy Lube probably does it multiple times per day

OP could leave the drain plug out and fill it with cornhead grease - or so I've heard.
