8AUG 2026 Piston Rings·25 min read What Is Piston Ring End Gap? Too Big vs. Too Small — and How to Measure It Piston ring end gap is the small gap between the ring ends once fitted in the bore — room for thermal expansion. Too small and the ends butt when hot and scuff the bore; too large and combustion gas blows by, cutting compression and burning oil. This guide covers why it matters, both failure modes, how to measure it, and why ring gaps must be staggered. With five animated diagrams.
