In most cases, a faulty lifter will be responsible for engine lifter noise; however, it is best diagnosed by a professional mechanic. Taking the vehicle with an engine lifter noise to a garage will allow professionals to place a diagnostic tool on the engine. If the cause of the engine lifter noise is a fault with the engine lifter itself, then it will need to be removed or rebored. Again, this is best carried out by a qualified professional.

It is easier to determine whether dirty oil deposits are responsible for engine lifter noise by simply changing the oil. If this stops the noise, then the problem is diagnosed and solved at once.

The third cause of engine lifter noise, a bent push rod, is another one that is expensive to solve. Drivers who occasionally speed and push their vehicle too hard are at risk of experiencing this problem. It occurs when the speed of depression on the push rod causes it to bend. In this instance, it will require professional replacement.

    What are the key features of a basic diagram of a combustion engine?

    A:

    The main components on a diagram of an internal combustion engine include the cylinder, which is the body of the engine, and the crankshaft, connecting rod, intake and exhaust valves, spark plug and piston. Fuel intake, burning and compression occur in the cylinder. The number and arrangement of cylinders in the engine determine the size and shape of the crankshaft, which rotates freely. The connecting rod, which connects the piston to the crankshaft is the primary mover in the engine.

  • Q:

    What causes a car to throw a rod?

    A:

    A thrown rod is usually the result of metal fatigue, insufficient lubrication or over-revving of an engine. When gasoline combusts in a cylinder, it drives the piston head downward, pushing the connecting rod and turning the crankshaft. If the metal is weakened, the connecting rod between the head and crankshaft may break. Poor lubrication can cause friction, and over-revving may produce more force than the connecting rod can handle.
