yes. If the engine needs to be taken that far apart, it is usually easier to remove it first. If you need to remove the pistons, then I’m assuming at least you plan to replace the rings. In many cases, the cylinder bore need to be worked on to get the best result and that would require removing the block from the car.

Depends on the circumstances, age and mileage. If the engine is in good shape but has overheated, and the oil control rings have lost their tension so the engine is burning oil, then yes this is OK to replace the rings.

Are piston rings easy to change?
Changing pistons rings is sometimes done, but usually you do is a full engine rebuild.

You must be very careful not to bend or break them.

What causes piston rings to go bad?
The cheapest way to “temporarily repair” this engine is to use a thicker oil than normal. The thicker oil will help your rings seal the combustion chamber better than normal oil. Keep doing this until the engine falls apart or at least wait until they get more worn.
Can you just replace piston rings without honing?
During engine operation, combustion faults often result in an accumulation and condensation of fuel on the cylinder wall. In this case, the oil film is thinned or washed off. The resulting mixed friction causes the piston rings to wear completely within a few thousand kilometres.
How often should piston rings be changed?
More often than not, you will need to hone your cylinder when replacing the piston rings. That is because honing creates small crosshatches in the surface of the cylinder, to allow the wall of the component to retain oil and provide lubrication for the piston ring.
