FAQ 

Q: Can I only replace piston rings if there is oil burning without cylinder liner wear?
A: Measure cylinder liner wear first. Single piston ring replacement is acceptable when liner roundness and taper are within tolerance. Complete overhaul including liner and rings is recommended if cylinder wall is scored or over worn.

Q: Why must piston ring end gaps be staggered?
A: Aligned gaps will form straight passage, causing gas blow-by to crankcase and oil passing into combustion chamber, resulting in blow-by and oil consumption quickly.
