Piston rings essentially seal the gap between the piston and the cylinder wall inside your engine. There are usually a few different types – a compression ring, an oil control ring, and sometimes an intermediate ring. The compression ring, as the name suggests, focuses on keeping combustion pressure inside the cylinder where it belongs, so you get the power you need. The oil control ring scrapes excess oil off the cylinder walls to keep things running smoothly and prevent oil from getting burned during combustion. They’re a critical part of what makes your engine go. Basically, when fuel burns, it creates pressure. Those rings keep that pressure contained so it pushes the piston down, turning the crankshaft, and eventually powering your wheels. Without a good seal from the piston rings, that pressure leaks out, and you lose power. They also contribute to engine lubrication by controlling oil consumption. You’ll notice if your rings are going bad. Usually, it starts with a loss of power – the engine just doesn’t feel as strong, especially when accelerating. You might also see blue smoke coming from the exhaust – that’s burning oil getting past the rings. Eventually, oil consumption will go up significantly, and you could even fail an emissions test. Replacing piston rings isn’t the easiest job, often requiring a complete engine rebuild, so it’s a good idea to address it early.
