Checking piston-to-valve clearance is an essential part of any engine build. In this tech installment, we show you how to do it. Aggressive camshafts and high-compression ratios are necessary for maximum power in an engine, but they also create a very risky relationship between the valves and pistons. HOW TO FILE-FIT AND INSTALL PISTON RINGS Another reason for the ring gap is simply because the ring must be split apart slightly in order to facilitate installation. There are dedicated tools, such as ring-expanding pliers that help engine builders install rings by holding the ring and expanding the gap just enough to clear the ring over the top of the piston and position the ring into its respective groove.
