Measuring piston-to-valve clearance is an important step to ensure the durability of your engine build.

Learn how to check your valve and piston clearance with a degree wheel for a more accurate measurement from Circle Track Racing Magazine.

We'll first measure the pistons, then hone the cylinders for precise piston-to-cylinder clearance.

Another factor that effects piston-to-cylinder wall clearance is the actual piston design. Depending on the location of the aluminum within the piston, it will expand differently in each area.

Measurements of piston friction force under operating conditions were made by applying the Floating Liner Method to a single–cylinder test gasoline engine. The measurement revealed how the piston ...
