Oil burning, lost compression or a knock from the cylinder can mean worn pistons, rings or bores. Before replacing pistons, measure the cylinder bores with the engine apart and compare them with the 4.060 in bore size and 0.0010 in minimum clearance below, since worn rings or bores can bring on those symptoms too.
