Changing the pistons will NOT fix an oil problem UNLESS you have a hole in the piston, which would cause many more problems as well. Placing new rings on the pistons, along with honing the cylinder walls (which is necessary if you are replacing rings) WILL allow the cylinder to seal better, improving compression and stopping oil slipping past the oil ring. It would be wise to check valve guides and seals as well if you decide to change the rings.
