Ticking Noise on Car Engine While Running

Car trouble symptoms: Ticking noise is heard coming from the car engine while it is running.

Car problem diagnosis: Ticking noise from an engine while running is an indication of an engine that is not fully lubricated. When a car engine is not fully lubricated, it can cause by a two reason, the engine is either lacks oil or has a low oil pressure.

To find out the real cause of the ticking sound problem you need to first check your car engine oil level. If the engine oil is low then the ticking noise you heard while the engine is running is cause by a poor lubrication of the engine. However, if the engine oil is not low then it does not lack engine oil.

Next check if the oil pressure is low. To check if the oil pressure is low, observe the oil warning light located in the car dashboard. If the oil warning light comes on while the ticking occurs, then the problem is also poor engine lubrication. Oil pressure is an indication if the car engine have sufficient amount of engine oil, if the oil pressure is sufficient the entire car engine key components can received an ample amount of engine oil, but if the oil pressure is low a certain engine component do not received an ample amount of engine oil therefore it can cause the ticking noise or tapping noise in engine.

Now what causes the oil pressure to become low? The most possible reason is a faulty oil pump.

However, if the oil pressure enough then the engine has a sufficient amount of engine oil. If this is the case then the problem is cause by a loose valve or leaking exhaust manifold.

That kind of problem can also cause a similar ticking noise, a loose valve slap against the rocker arm while the engine runs thus causing a ticking noise. Leaking exhaust manifold causes the exhaust gases to leak thus causing a ticking sound on the engine.

Auto diagnose caused: Poor Engine lubrication, loose valve or leaking exhaust manifold

Auto zone advice: If the problem is poor engine lubrication and the cause is a lacking engine oil then just add the engine with a sufficient amount of engine oil, however if the poor engine lubrication is cause by a low oil pressure then you have to bring your car to a reputable auto repair shop and ask the mechanic to check the oil pump if faulty and the oil pan if it clogged.

However if the problem is a loose valve or leaking exhaust manifold bring the car to a reputable auto repair shop to determined which of the two is the cause of the problem of having ticking noise while the car engine is running. It might only need to tighten the valve, provide that the car has adjustable valve.
