Can't remove cam retaining plate I'm changing cams and the last hex bolt for the plate won't come loose. It feels like the guy that put the original motor together used Loctite because the other bolts were an bear to break loose.
Now my big problem is the inside of the hex bolt rounded out. I tried to get vice grips on the outside but because it is recessed, I can't get a god grip.
Any suggestions?
Thanks.

You could try "cutting some teeth " on the outside of the bolt with a chissel and use a "GATORGRIP SOCKET " which has needles inside the socket to conform to rounded off/ rusted bolts and such. The "teeth" you make with the chissel are to help the gatorgrip socket hold onto the bolt head, just be patient when making the teeth and don't wail on the chissel, you just need to make the outside of the bolt head a little rough for the socket to work. This should work for you, just take your time and buy the right bolts when you start to put your engine back together. Good luck ! 
A lot of guys seem to use red Loctite like its butter, not sure why. Try putting some heat on it, you may need to replace the retainer plate after but its relatively cheap. You don't want to be attempting to drill out this bolt.

I stand corrected then. I used the howto guide and it called for it so I did. I've used loctite on tons of other bolts before and they had no problem coming out, weird 
Good luck getting it out let us know what does the trick.

yeah i didnt loctite mine only becuse i didnt have any laying around otherwise i woulda, just the thought of the head of one of thoes bolts comeing out and hitting one of the holes on the cam sprocket gives me chills 
What do you mean when you say the "inside of the hex bolt is rounded out"? How does the inside of a hex bolt get rounded out and why does it matter if it does? You should contact the "guy who put the original motor together" and ask him what he used. If you use locktite you should try blue not red in these low torque applications. You may have to use a quick hard snapping motion with a breaker bar and a 6pt socket to fracture the locktite as is done on the rocker bolts which are held in place by locktite from the factory. Once the locktite on the rocker bolts is fractured you can unscrew the rocker bolts with your fingers. You should be able to do the same thing with the cam plate bolts as well since they have a similar low torque value.
Just an FYI, I have the GM manual and it does not call for Loctite. It will expressely say so if it does. Torque to 18 ft/lbs.[/QUOTE]
Word, I didn't use any either. The general didn't call for any, so I left it out. I guess it couldn't hurt though. I didn't notice loctite on any of the factory bolts I removed.

For anyone who is interrested, I got a kit that consists of sockets that fit over the head of a rounded off bolt. THey have machined in "blades" that are similar to rifling in a gun barrel. They fit snug on the bolt (lightly tapped with a hammer) then put a ratchet on it and loosen. It digs in as you loosen. It came right out effortlessly. Best $20 I ever spend. Also purchased the correct bolts from the dealer.
Glad to hear you got this done, hope the rest goes well. Any more info on the kit you bought like part number of something? Sounds like something worthwhile to have in the tool kit
