5 Causes of Engine Ticking Noise at Idle and Accelerating

Proper maintenance and care are important for keeping your car performance always at its best. Besides regular checking to a trusted mechanic, it is advised for users to understand some basic guidelines of handling problems that may appear.

One of the familiar problems found is unusual sound that comes from the engine. It is in fact, car engine produces noise as numerous parts inside of it make movements when it operates. However, there may be some problem waiting to fix if there is unfamiliar sound heard like ticking noise. This ticking noise can even be heard when car is idle or shortly after oil replacement. To know what exactly the problem is and to get your car the right fixing, here are the most common five causes of engine ticking noise at idle and accelerating.

The Amount of Oil is Low

The first cause is low oil. Frequently check the amount of oil unless you will find the valve train components are not thoroughly lubricated. Dry valve train components will cause them to produce ticking sounds. If you notice this low level of engine, watch for the possibility of leakage at certain parts. Leakage can be the result of broken and worn out parts such as gasket or seal.

As the engine also needs oil to cool down, the chance of low level of the oil is also indicated by overheat engine. Ticking sounds which are caused by any of those symptom is greatly related to low level of oil.

Problems in Reciprocating Components

There are reciprocating and rotating components in cars. When the appearance of ticking noise is assumed to have relation with certain components, it is very likely the reciprocating components which are involved. Ticking noises can indicate the need of replacement of components such as pistons, valves, and push roads due to long term of use, breakdown, or other forms of malfunction.

Poor Bearing Attachment

Another problem among common five causes of engine ticking noise at idle and accelerating is poor bearing attachment. Bearing which is poorly attached to the rod will result in knocking around rods so the ticking noise appears. This bad attachment, too, is caused by worn out part (bearing). This condition has impact on the RPM engine. The problem needs immediate solution before it gets more severe.

Valves Not Properly Set

It is advised to check these parts at first place once you notice engine ticking sounds. Valves which are not adjusted are said to be the greatest cause of this problem. Proper adjustment is responsible for the valves to open and close when the engine operates. These close and open movements are managed by rocker arm and there is camshaft with pushrod which is responsible for the rocker arm to work. All of these parts have to be specifically located from the valves. False adjustment will result ticking sounds because faster move of the valves at shorter distance.

Firing of Fuel Injectors

The last common five cause of engine ticking noise at idle and accelerating is caused by firing of fuel injectors. However, not like other symptoms previously discussed, ticking sound which is caused by fuel injectors starts firing is not indicator of certain problem. It happens to particular types of cars with fuel injection system. The ticking sounds occur because the fast opening and closing movements of the valves when sending the right amount of fuel to the internal combustion chamber. Therefore, the ticking sound in this case is just a part of a whole normal process taking place in your car.
