Get Your Gap Right — Piston Ring Gap Explored

Whether you’re rebuilding a factory engine with a stock bore size or you are going to an oversize bore and fitting factory oversize pistons and rings, in most cases, the rings come pre-gapped, meaning they’re already set for the bore diameter. This means that once installed, they’re good to go. When fitting an aftermarket forged piston, however, you will most likely be working with ‘file-fit’ piston rings. In this article, we’re going to explore how to select, measure, and adjust your ring end gaps to help achieve a reliable ring seal.
