(4) Oil control ringThe oil control piston ring has a spring that is installed with the ring. The gap in the spring should be a distance of 180 degrees from the ring end gap when the oil control piston ring is assembled. The colored portion of the spring must be visible at the ring end gap.Width of oil control ring groove in new piston ... 4.041 0.013 mm (0.1591 0.0005 inch)Thickness of new oil control ring ... 3.982 0.008 mm (0.1568 0.0003 inch)Clearance between a new piston ring groove and a new piston ring ... 0.038 to 0.080 mm (0.0015 to 0.0031
