What makes piston ring selection and ring endgap so important to engine life and power? What's more, what makes that first engine firing so critical to proper break-in and longevity? Those first few ...

Repeated cycles of searing combustion heat alternating with cool incoming air and fuel, extreme load reversal, thrust forces that slam the pistons into the cylinder wallsits quite amazing that ...

No matter how much we love them, our engines are still basically inefficient air pumps and need all the help they can get to make power. Like any other type of pump, if it leaks, it won't work. And ...
