1 Measure side clearance of pistons rings between piston ring and piston ring and measure mounting groove in the piston using a feeler gauge.
Press piston ring on the measuring point into the radial groove.
If side clearance of piston rings is too high: replace pistons and piston rings.
The engine oil consumption will increase disproportionately for a large vertical clearance of piston rings.
