What should the pressure be on a piston ring?
The cylinder pressure from 50 to 75 percent and eventually to 100 percent load will place additional pressure on the back side of the rings which will quickly establish the proper wear pattern for seating.
When do you Know Your piston rings are worn out?
A top or second ring that exhibits full face contact should be considered worn out. Proper ring performance and sealing is based on the rings sliding across a coating of oil between the ring and the cylinder wall in much the same fashion as a crankshaft journal rides on a thin film of oil between it and the bearing.
How to break in your piston rings, the right way?
The ideal combination is to tune the engine so that it starts on the first or second revolution. For carbureted engines, this means pre-filling the fuel bowls and accurately setting the initial timing. As soon as the engine starts, immediately bring it up to an above-idle speed.

How is the sealing of a cylinder based on?
Proper ring performance and sealing is based on the rings sliding across a coating of oil between the ring and the cylinder wall in much the same fashion as a crankshaft journal rides on a thin film of oil between it and the bearing. Glazing is a term often used when discussing a cylinder that is not broken in properly.
