ADDITIONAL INFORMATION

Plateau honing is a special process which has generated interest in the engine manufacturing and rebuilding market ... and for good reason.
Typical honing leaves a series of microscopic peaks and valleys in a cylinder. The valleys created during honing act as oil reservoirs to provide lubrication when the engine is running. The peaks, on the other hand, are worn off by the piston rings as the engine is broken in – thus leaving a plateaued surface above the valleys.
