Is the piston skirt the portion that is cut out on one side or is that the piston crown?
Piston crown is the top, skirt is the side below the ring lands (ring grooves). The as you say, the skirt often has cut aways to clear the counterwieghts on the crankshaft.
What is the piston crown?
The central part of the top of a piston, often raised in some engines.
What is the position of piston ring?
Generally in grooves near the top of the piston. The compression rings, near the top and the oil rings at the bottom of the top. The ring gaps are staggered.
How do you install piston rings?
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.

How do you find the marked face of the piston ring?
The compression ring will have a dot or indentation marking the top of the ring .
What is the crown of a piston?
The piston crown refers to the top of the piston. A piston can generally be divided into two sections (though the piston is a single piece). The lower part of the piston is called the skirt. The upper part, including the top of the piston that faces the valves and must handle the combustion of the fuel-air mixture, is called the crown. The piston crown must have the mechanical strength to withstand the forces of combistion, and must be made of materials that will withstand the heat of combistion. All this must come in a package that has limited thermal expansion so that the tolerances within the engine are tighter and performance is maximized.
Is there any difference between piston rings of naturally aspirated engine and turbo charge engin?
Yes, the material, thickness and possibly style of piston ring(top ring) can be different.
Does the steel ring go on top of piston or on second grove?
Yes , the steel(compression) ring goes on top ; see the related link to a video tutorial .
Where do the piston rings line up on the piston of a 1999 blaster?
There should be a arrow on top of the piston close to the pistons edge. Your top ring's gap should be on same side as arrow. Then alternate next ring 180 degrees from last gap. The arrow should facing forward when installed into the jug.
When a piston has three ring the bottom ring will be?
Most commonly the bottom ring will be the Oil Controlring.(Control added by amclaussen.)Oil control ring is correct. It is used to keep the cylinder lubricated as the piston goes up and down. The first two top rings are for compression. However, the 2nd from the top ring is also a wipper ring. Used to keep oil from getting into the combustion chamber.(~Decker)
Where does maximum cylinder bore wear normally occur and why?
most cylinder wear occurs at the top fo the ring travel. Pressure on the top ring is at a peak and lubrication at a minimum when the piston is at the top of its stroke
