So I was changing my oil, and somehow overtorqued the drain plug and it cracked in half (threaded part stuck in the oil pan). Any tips on how to get this fixed?

Should I try getting a screw extractor? Or Should I take off the oil pan, take to machine shop..

Pic of remaining bolt:

 

you may need to tap it to get the rest out,. pic of piece that came off ?

 

You need to buy a set of gator grip sockets...best investment always yields new tools

 

If it is not a tapered thread you should be able to remove it easy since the head snapped off. You would only have the friction between the threads which shouldn't be much.

Attempting to drill would only spin the threads and make your issue bigger if the snapped bolt spins through the hole.

Put the drill in reverse and put a rubber vacuum cap over a dull bit and try to spin the threads back out.

 

Thanks for the responses, updated 1st post with pics of the bolt that snapped off...

 

Ah now that I see pics counterbore, and helicoil would do it if it gets seriously damaged or wont budge.....Ive pulled plugs the same way when old ceramic goes bad,lol

 

dude, why risk any of the above suggestions..

just remove and replace the lower oil pan..

replace the pan?

OP apparently does not want to drop the pan though. Otherwise, you could do any number of things, least restrictive and external methods are what he seeks it appears.

 

I doubt that?? he states in his first post:

if he's willing to remove the pan, then i doubt it, and the cost of any machine shop work?? pff, a new oil pan is probably cheaper than that...

anywho, its all up to him....

Yes replacing the oil pan would probably my last option if all else fails .. but if I could do something less restrictive and viable then I'd definitely opt for that solution... appreciate all the suggestions...

 

I consider myself a perfectionist.. with that said, replacing the oil pan with a brand new one would be my satisfaction first and foremost but that's just me. looks like a very easy DIY too but to each his own

 

When something breaks, I take that opportunity to upgrade the item.

Get a new oil pan, whether it be OEM or an aftermarket one. It's an easy fix. (On a scale from 1-10 for difficulty... it'd be a 2)

 

How is it that a perfectionist over-torqued the drain plug in the first place? Didn't you use a torque wrench?

Any idea how much torque you actually applied to the plug?

 

I'd drop the pan, extract the bolt and replace the pan, unless the pan is cracked or stripped then I'd just replace the pan. Any machine work is going to cost you in tools or labor.

 

Wrong perfectionist. he is not the OP.



Now with those update pics...ouch. You may have boogered up the threads to where you wont get them out. If so, just buy a new pan and replace yours.

 

What did you use? A 4 foot breaker bar? I've never seen that happen before lol.

 

Update:

I was able to remove the stuck drain plug piece with quite a simple solution, I was able to rotate the stuck piece off using a small flat head crew driver lol.

I guess the shape of the stuck piece had an area where you can simply rotate it using something small such as a small screw driver if that makes sense, don't really know how to explain it other than showing it visually. Just imagine the shape of the stuck piece based on the images I posted.

In short, the stuck piece can be rotated counter-clockwise with minimal effort since the hole itself is already lubricated. This should sum it all up

Thanks all, note to self, follow the recommended torque specs.

 

Good that you got that out op, lesson learned.
