Cam & Valve Train

Cam & Valve Train

Valve trains are responsible for the opening and closing of each of the valves in your engine. They consist of a number of key parts including rocker arms, pushrods and lifters; and help to control the amount of air and fuel allowed into and out of the valves. The opening and closing motion is controlled by the camshaft, that is kept in order by the timing gears, belts and chains. Valve trains have to be made from strong and durable materials that are capable of handling the extreme heat and pressure generated by, and inside the engine. This great pressure and stress can cause cracks to develop in the valve train, but this is something that is likely to happen after a significant mileage and is highly unlikely to just happen all of a sudden. Reduced efficiency could be caused by damaged valve trains, and they will need to be replaced rather than repaired for a quicker and more effective solution.
