Guys, I need some ideas here.
I managed to round off the allen head coolant plug in my block. I used a 1/4" Allen head socket, which is the right size as far as I know. It fit very snug, but the inner part of the plug stripped so easily, you'd think it was made of play dough.
The 6 sided plug became one big circle within the plug. It no longer has any sides.
Plan B... I tried to JB weld the 1/4" Allen socket into the plug. I let it dry for 24 hrs and applied some torque. Failed miserably.
I have no clue what to do now. How do I get this thing out without pulling the motor? Does anyone have any ideas? Please help. I've been screwing with this thing so much I am afraid to just leave it in there. I have an aftermarket K-member, so there is plenty of room to maneuver.
And yes the freeze plug in the pic is leaking... that was my whole motivation behind trying to drain the coolant via that stripped plug.
I was thinking about actually spot welding the allen head socket to the plug, but thought I'd consult everyone before trying to find a welder
Thanks, Luke

try vise grips or an easyout first

can you get a hammer and a chisel in there?
looks like you may have enough room.
put a little heat on it if you can.

second thought maybe you can beat an 8mm allen into it and then use vise grips on the side of it while giving it a go with the 8mm.
If you can get an 8mm beat into it you can also use an impact screw driver but with an 8mm bit.
You know the ones you slap on the back and they turn while you do that.
Guys used to use them on the phillips head bolts on old honda motorcycle cases.
harbor freight sells them.

why don't you drill through it and pound in an easy-out? you will only get minimal shavings in the block if you are careful in your drilling, which will come out easily once it is flushed.
good luck.

Do you have a torx bit of roughly the same size? Pound it in there nice and tight and see if you can twist the plug out. I've done that a couple times with rounded out allen heads...

Spray some penetrant then get some vice grips on there and hit it with a hammer to shock it loose..

Just drill it out and use a easy out! why bother with anything else? Dont fight it with Vise grips If you dont feel comfortable doing it bring it over.

thanks for the suggestions guys
what is "easyout"
never heard of it
Oh, and there is no way in hell I can drill due to not having enough room to work.
I have maybe 2 inches before the header going straight out from the plug...
Any other ideas?

an easy out is basically a reverse threaded drill bit.

I've used them before, MAKE SURE YOU DONT BREAK THE EASYOUT!!
it can't be drilled!
I would personally just drill that plug out, that should break the tension on it, letting you get a pair of vice grips to turn it.

Drill + Easyout. If the header is in the way, take it out.

so you drill a hole, hammer the eay out in, and the turn counter-clockwise?
Is that how the easy out works?

I believe drill the hole, turn the easy out clockwise to get it into the hole some, then counter clockwise to remove both together.
The reverse threads should dig in when you turn counter clockwise.
Sorry been a little while since i used one

Luke, if you CANNOT get it and can tow it I can have it removed at my shop.
BUT, if you can do it there, take a torch and heat up that area to break down the lock tite/sealer they use at the factory. Not sure if you can grab it at all on the inside, if not, next time you know to heat it up first

Or if you have a dremel, slot the plug like a flat head screw and then use a chisel in the slot and a hammer to break the thing loose...

Get a punch and hit all 6 points,then hammer on your socket..heat up the area around the plug only...longer the better. If you can get a impact in there using swivels & extentions with 25 degree angles..should work. otherwise you need the welder.

you can always just leave it be.
I doubt it will leak if you cant even budge it.
drain your coolant from the freeze plug once you hammer it out.

pull the header and everything else out of your way and drill the thing out and use an easy out. Otherwise you will spend hours fighting with it. I would also apply some heat to that area prior to turning the easy out. Welding a hex key is only going to complicate things in my opinion, though that will get some heat in there..................

um.
some of these suggestions are a little out there...a good pair of vise grips...get it on there as tight as you can....and turn it slowly...should back right out.... i would think....

Yes exactly.Leave it alone and change the freezeplugs out.It isnt going to leak and really there is no reason for you to have to drain the water from there.

not going to happen,not enough room and material showing to do so.
