There is a sharp noise in my car's (16V) engine for last few months. There is no smoke or difference in performances. I noticed that earlier, sound comes about two minutes after the engine starts and which disappears when revs above 1500 or 2000 rpm's. Now, the sound comes as the engine starts. I changed the oil couple of days back, 5W60. Is this due to dephaser pulley, hydraulic lifters or any other thing. Please watch the attached video. Any advice, suggestions please? Thank you very much in advance.
