I know it's nothing crazy. I think it's like 23 ft-lbs. Don't quote me on it though.

You can extract a plug. You are going to have shavings inside though, good luck cleaning.

How is it stripped? Crossthreaded or wrenched?

Do you have a pic of it? If the plug blew out, youre saying it blew the insert/threads also?

It's going to require you to remove the head if you want to do it right, if not it CAN be done with the head still on though I wouldn't advise it.
