Review on Camshaft Actuator Retainer Sprocket Compatible by Nick Moo

When I opened the box it looked like a quality tool but I had to fiddle with it a bit to fit it in the jaws. As for the "blocking" of the cameras, as you can see from the pictures it doesn't block anything. The shaft bent immediately and the camshaft chain jumped over the teeth. This thing lasted the whole 45 seconds. Don't waste your money on this junk.
