My Drain PLug will not come off!

Ok guy's I've pulled and pulled on my drain plug with my 6 point socket and breaker bar and the drain plug just won't come off. My hands are badly blistered and I'm running out of ideas to get this off. I think the previous owner wore out the drain plug, because its not perfect,you can see its rounded off in some areas. How can I get this thing off?

Oil pan drain plug? Give it a good tap with a hammer and then try... Can you just not crack it loose? or is it just totally rounded off? If its rounded off get a pair of vise grips on there... and then try

ok ok - so it just won't turn? or its stripped?

If it won't turn try heating up around the bolt a little....are we talking oil pan drain plug, or tranny?


BTW, have you ever thought about joining a gym? j/k

I've already tried a hammer and it didn't work, and yes it is almost totally rounded off, I will try using vice grips though.

Heating it up sounds like a good idea, I'll give that a try. Oh and it's oil and it is stripped.

? For some reason it messed up on the quotes. I quoted both or your messages and I guess for some reason it used the ending quote on DC350's and the beginning quote on classicauto's. Sorry about that.

I had a tough time taking mine off under the car, it's hard to get proper strengh lying on a creeper, i used the two wrench cheater bar trick to do it, but make sure you are VERY carefull not to strip the bolt any more than it already is, your problem will be much bigger.

Also, you may consider getting a new plug if you think it will be a problem in the future.

Try using some Vice Grips, they work really good. I had to use it for a stripped bolt when I was changing out my power steering supply/return hose.

get the size on a 12 pt socket or if its a metric drain plug try getting the sae size close to it and force it on the drain plug with a hammer and get yourself a big 1/2 inch breaker bar. its going to be harder to do like jacked up in your driveway, you might want to bring it in to a shop, thoes things are alot easier to do on a lift

make sure you have a new drain plug to put on after you take that pos one off of there.

You need a socket that doesn't grip the corners and the correct size, 19mm I think.
Find someone with a Metrinch socket. Metrinch sockets will grip rounded bolt heads and nuts. I'm in FallRiver for work if you want to borrow a socket.

SK tools also has their turbosockets which can also take off rounded bolts.

Sears sells the Craftsmen "bolt-out" set.

I'd wager that SnapOn/Mac/Matco/.......probably have equivalent products.

Also, spraying the drainplug with Kroil/WD40/CRC/penetrating oil/.... for several days will help with removal.

I've also used small plumbers pipe wrenchs. They'll grip round pipes. Rounded drainplugs are 'piece of cake for a pipe wrench'.

I've never needed to drill cut weld saw torch a drainplug. A penetrating oil, + the correct socket mentioned above or the pipe wrench, will work always!

but seriously put on some penetrating oil and buy a new plug before you yank out the old.

Same exact thing happened to me. It was rounded off and malformed into the shape of an egg.... yeah, I know that is strange.

I got out my handy pipe wrench. It has angled teeth that are made to bite into a pipe when you turn the wrench. I sized it down, fitted it onto the head, stated turning it so the teeth bit into the head of the bolt and popped it right off.

I also went down to Pep Boys and picked up a new oil drain plug with a Teflon sealing washer for like $1.45.

Give this a shot, it should work no problem.

this is the time you go down to pit stop or such (not walmart or jiffy lube!) and have them change the oil. then you dont have to worry only as a last resort tho. and wath them closely too, they may screw you, but theyll get it out

I finally got this off, I used PB Blaster and a long breaker bar. Not looking forward to changing the differential fluid because these bolts were on so tightly, that one's sure to be overtightened too.

just be carefull.....BLAST the hell out of them about a week ahead of time (1 or 2 times a day) before you attempt to loosen them...use that PB blaster..its good stuff...maybe buy a little propane torch and heat them (BOLTS) up pretty good right before you do it also...dont worry about the PB blaster its not flamable!
