Feeler gauges are used for all types of general clearance measurements such as spark plug gaps and ring gaps of installed piston rings.
How to use a feeler gauge:
Thin blades of metal that are labeled corresponding to their thickness. Feeler gauges are used for all types of general clearance measurements such as spark plug gaps and ring gaps of installed piston rings.
Feeler gauges as seen in Basic Engine Building:
During pre-assembley you want to install a piston ring in each bore and check the clearance with feeler gauges. File the rings or use a ring grinder until the desired gap is achieved.
