Works well after a small repair.

I had to bend the heads of the hex bolts maybe 1/16 inch, the gasket not the outer shell of the tool didn't go over it, you can see in my only photo how I ground down the heads for the proper release. After this tool worked flawlessly, another one was added to the toolbox. FYI, only works on 08-10 6.4 not 6.0, they use a different tool.
