Tapping noise in my Aveo Engine - 38k I have been observing a tapping noise from the engine bay since a week now. I did some research and found it to be an hydraulic lifter issue. The noise is exactly the same as in the video below except its a bit softer than the one shown here. Mine is a CNG vehicle and all other parameters are normal. The car gives a superb mileage of over 15 kms to a kilo of CNG. Oil levels also seem to be ok when i saw the dipstick a few days back.
What can be the possible causes and remedies for this noise? |
