I like that air chisel idea...
Good job, hillbilly. LOL
A friend tried one of those rubber expandable plugs on his MoPar six, after it built up pressure during the warm up test it popped like a giant high priced wine bottle, bent the inner fender and sprayed his brand new anti freeze all over the truck and surrounding area, he figured out a way to get a steel one back in, LOL.
