How to check Pistons, rings and cylinders using feeler gauges

We all know there are tight tolerances in engines and that micrometers are often needed to take accurate measurements. In this video I've tried to show how you can check if your pistons, rings and cylinders are within specification, using only feeler gauges.

Good explanation and a sure way to check the piston clearance, even if you have the bore guages and micrometers this is a good extra check.

Excellent explanation

Glad it was helpful!

Excellent explanation. I've never known there was such a big difference in the piston diameter at the top and bottom. Is this just because of the heat of the flame front which expands the top of the piston?

[@aldermarsh6776]

That's correct. It also explains why engines smoke more when cold because the ring pack isn't fully activated until the piston is at temperature, and the "looser" rings allow oil past them.

Have you got any nylon.. Let me have the basic size you require
