Grinding Piston Ring End Gaps

Get into the fine details of engine building as I walk you through the precise process of grinding piston ring end gaps for my Small Block Chevy. Achieving the perfect gap is critical for cylinder sealing, performance, and engine longevity.

In this step-by-step guide, you will see:

How to set up and use a manual piston ring filer for a clean, perpendicular cut.
The proper way to seat a ring in the cylinder bore using a piston to ensure an accurate measurement.
My calculations for determining the exact number of turns needed to hit the target end gap.
How to use a feeler gauge to measure and verify the gap at the bottom and top of the cylinder.
I also show the final data table for all 8 cylinders and discuss how cylinder bore taper affects the final clearances.
