Piston rings are the seals in your cylinders, giving you better compression and power, but what happens if they wear or break? And how can you spot the signs?

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 ...

A knocking sound from the engine often triggers worst-case assumptions, but piston slap is a far more common—and usually less dangerous—culprit. It occurs when a piston lightly contacts the cylinder ...

Cylinder misfires can turn a smooth commute into a rough, fuel‑wasting slog, and they almost always leave a trail of diagnostic clues if you know where to look. I focus on four of the most common ...

Here you can see basic piston terminology, including major and minor thrust locations. Of particular note is the fact that piston pin offset can be used to counteract combustion pressures on the ...
