help stripped bolt head

[96mcls]

i stripped one of my head-block bolts while trying to remove it.
how can i get it out? i was thinking one of those things they have on tv that removes stripped bolts(i think it's a craftsman), but i don't know if it will work on a bolt under that much torque


PLEASE HELP

Grind a slot in it and use a big screwdriver. You may need to use vice grips on the screw driver for more leverage.

Next time use the right socket size.

lol, that sucks... one of those special sockets that remove stripped bolt may work.

try betterthanyou's idea or you can put several rags around in the intake area and around the bolt to catch the filings.
then take a small drill bit and drill in the center of the head bolt (about 3/4 inch down
use a punch to mark the center.
then go in steps bigger and bigger untill you the top of the bolt comes off
then you pull the head up off the motor, and take a plumbers wrench
commonly refered to as a"monkey wrench", aka pipe wrench around the bolt on the shank and it will come right out np

yeah i was using the right size, only it was a 12 point socket, so pretty much all the force was put on the weak corners, i grabbed a 6 point, but the damage was already done but i stopped before it was totally killed, so hopefully i can use the stripped bolt remover
i don't know how great a screw driver would work, seeing as with a 17 inch breaker bar they are pretty hard to loosen

Then removing the bolt head and sliding the head off is your best bet.

that was my plan if the special socket doesn't do the trick.

and thanks for the help

The extractor sockets will take a lot of torque. I've had my 3 foot breaker bar on one, putting as much force as I could to it. They work well.

i got them out with the extractor socket

okay i have another question, i have lost 2 of the exhaust manifold studs and nuts , can i just replace them with two regular bolts?

[bszopi]

I wouldn't. Even the regular exhaust studs and nuts tend to loosen over time, and I'm sure a regular bolt would be worse. Besides, a header bolt/stud and nut won't be much more expensive than a regular bolt. Just bring in one of the ones you still have to a parts store and match them up. You'd be suprised what they have in some of the bins behind the counters.

cool i didn't think autoparts stores would have anything like that, i have already been to the dealership once today, i didn't want to drive all the way back just for 2 little studs, and i don't know and close boneyard i could get them from. any who i will stop blabbing and get back to work on the engine.
thanks

Use a mig welder and weld an old 15MM 1/2" socket through the socket to the bolt head. You may have to drill the socket through to 1/2" to get the welder in. Use caution, the aluminum head could easily be damaged.

okay well, no parts stores have the exhaust studs, all they carry is ones for chevy and ford small blocks.
haven't called the dealership yet, buti have till friday when i get my heads back from the machine shop.

[RednBlack]

I'm not sure where you live, but your machine shop should have access to any stud you need.

i live in the dallas-fort worth area(north texas)
and i will see about the studs when i pick my heads up.
