I was also wondering why this tool hadn't been discussed here before. Yes, I am planning on doing a LIMG job sometime in the near future. I mentioned it here:

Just came acros the tool on Amazon.com and was wondering they it had never come up here before. If I can make the job easier I will. I've never done anything remotely like e LIMG job. Closet thing would be a valve cover gasket, but I've done plenty of other harder stuff to do I am sure.
