This is not necessary, but makes valve adjustment much easier. I did a CRV without and then did a pilot with it, which speeds things up a lot. I will say that it has only two small disadvantages. The first is the rubber grip. It doesn't seem to stay at the same level when it gets oily, which it will when working with valves. The second small issue is that it's too long in some places on the motor and I had to use a socket and screwdriver separately to get to where it didn't fit.
