No, it cant.
Poor piston ring sealing in diesel generators can be caused by damage or misapplication. If a diesel generator is left running under a low load it can cause poor piston sealing as well.
The purpose of a piston ring expander is to make it easier remove and install piston rings. Because of the low torque they use, they help to prevent damage to the piston rings.

Yes it is, cause when a engine is running it builds pressure inside the crank case, and to much oil will cause oil leakage in the gaskets and could cause piston ring damage.
You have to disassemble the entire engine, remove the piston and check the rubber ring around that piston.
The only way to "check" a piston would be to remove it and visually inspect for damage and wear.Make certain that the piston is not cracked or otherwise damaged.check the ring grooves. Use a piston ring and a set of feeler gauges to determine the amount of wear. Excessive ring groove wear can result in piston failure and if the piston shatters, it can cause the engine to fail completely.Next, use a micrometer to determine the difference in the diameter of the piston between the top and bottom. The piston will wear and if the difference between the top and bottom is too great, the engine will exhibit "piston slap".Check the fit of the wrist pin, it should be tight.HOWEVERYou can run a compression test and get a good idea whether the piston is functioning somewhat correctly.
If you do, you will only do more damage. Time to overhaul or replace.
The DNJ ring spec. information, printed on each compression ring (located next to the piston ring gap), is installed facing the top of the piston for both the top (#1) and middle (#2) compression piston ring slots. The oil control ring can be installed just like any other oil control ring in the bottom (#3) piston ring slot.
a piston ring is not calibrated. You just slide the new one in place
