Filtering Out Future Problems Papillion NE

Filtration is all about trapping contaminants. The engine’s oil filter traps wear particles and dirt that might otherwise damage the bearings, rings and other wear surfaces inside the engine. The engine’s air filter keeps out dirt that could damage the piston rings and cylinders, or clog air passages in the throttle body idle air control circuit. The transmission filter prevents debris from jamming control valves and causing wear inside the transmission. The fuel filter stops sediment and rust particles that could plug the fuel injectors. By stopping unwanted contaminants before they can cause trouble, filters prolong the life of the engine, transmission and fuel system. The more contaminants a filter traps, the more efficient it becomes – up to a point. If not replaced for preventive maintenance, the filter will eventually clog and create a restriction. This, in turn, may cause additional problems.

Hustle & Flow

A clogged oil filter may restrict oil flow to the bearings, camshaft and upper valvetrain components. This may force open a “bypass” valve that allows unfiltered oil to flow around the clogged filter. If the oil is dirty, the contaminants will be carried directly to the parts that the oil filter is supposed to protect. This will increase oil wear and may even result in premature engine failure.
