Simply place the cylinder you are working on at the top dead center, thread the tool into the spark plug hole, and fill the cylinder with compressed air.

The perfect and affordable tool for the job.
I had to rebuild the 5.3L v8 in my 2010 GMC Sierra 1500. Part of the build was replacing the valve springs and the valve stem seals so that I could run a performance camshaft. With a little grease on the screw threads andvwashers this tool had made short work on getting the job done. I have two other LS series motors that will eventually need some work, so this tool will definitely come in handy when I begin the rebuild process on both of them.

LS3 Springs
Worked as intended for both sets of heads with factory springs. Keeping the threads oiled will keep it from striping. mild wear but good piece for the price compared to the big name tool.
