Troubleshooting car problems of ticking noise in engine while runningEngine ticking noise is commonly an indication of poorly lubricated engine. The reasons is the oil inside the engine is not much or just simply it lacks engine oil or might be the oil pressure inside the engine is low.
With that said the focus of troubleshooting this kind of problem is limited to checking of the engine oil by doing the following.
1) Lift the hood of your car and locate the dipstick for the engine oil.
2) Remove the dipstick and wipe the end portion that dip with oil using clean cloth.
3) Put back the dipstick on the original location (dipping it again on the engine), and put it out again and check the reading. If the reading is below the full line then the engine oil is low.
When the engine oil is low then the engine is poorly lubricated. This causes the engine ticking sound that you heard coming from the engine.
If the dipstick reading is within the full line this means that the oil level is enough and bring us to the next possible reason of engine ticking which is a low engine oil pressure inside the engine.
Now to confirm if the oil pressure inside the engine is low, Observe the oil indicator on the dash board, if the oil indicator light comes on while the ticking sound occur then it is a case of low oil pressure. Otherwise, it is a leaking exhaust manifold or a loose valve is causing the ticking sound in engine.
When the oil pressure is low not enough oil will reach most of the engine components causing ticking noise from engine. What causes the oil pressure to become low?
The oil pressure will become low if the oil pump is faulty or if the oil pan screen is clogged.
Possible Car Trouble: Poor engine lubrication because of low engine oil level, low oil pressure because of faulty oil pump or clogged oil pan screen, loose valve or leaking exhaust manifold.
Free car diagnostic recommendation:
Engine lubrication is poor. Add enough oil in the engine. Consult the vehicle owner’s manual for the type of oil to be added.
Oil pressure is low. Bring the car to the car shop to determine whether bad oil pumps or a clogged oil pan screen is causing the ticking noise in engine and repair if necessary.
Exhaust manifold leak or loose valve. Bring the car to a shop and ask the mechanic to check for any loose valve in the engine or a leak on the exhaust manifold. Sometimes a valve adjustment or a tightening of loose bolt on the exhaust manifold can solve the problem of engine ticking noise that cause by this car problems.
