In order to prevent heat build-up that can lead to piston damage, it is important the correct level of lubrication reaches the piston at the skirt and piston pin. Wagner advises technicians to examine piston oilers. “Many of these are very delicate in relationship to other parts of the engine and are bumped easily, resulting in either a broken or improperly directed oiler,” he says.

Contamination wreaks havoc on pistons, too. Water contamination cause erosion and fuel and lubricant dilution. “Contamination can be water, fuel, particulates from the air intake or foreign objects,” says Wagner. “Particulates can wear the ring lands, resulting in increased oil consumption. Foreign matter can be anything including nuts, bolts, valve train or turbocharger parts, and much of the time foreign matter in the combustion chamber is the result of another component failing.” Be sure to use the proper Diesel Oil.
