What is Rocker Arm and How Does It Work?

Rocker is located between the intake and exhaust valves and pushrods which are connected with crankshaft below the engine. When the crankshaft rotates it cause up and down movement of the pushrods, then the pushrods pushed and pulled the rocker arm to rock up and down which cause opening and closing of the intake and exhaust valves. The broken and loose rocker arm cause poor performance of the engine, the engine will be enable to take the full load of the vehicle and in severe cases engine failed to start.

There are also many other possibilities which causes of strange noises in the internal combustion chamber like worn crankshaft, warped valves and lack of proper lubrication for moving parts of the engine. If you don’t find any visible fault in the rocker arm but you are still hearing strange noises then go to the mechanic to fix this issue.
