As a result it is definitely a noise result from engine itself...<br /><br />I have tried to change the 10w-40 engine oil and all 4 spark plugs but the noise still persist...<br /><br />Any idea what happened? Could it be the bearing of crankshaft? eedwinc The Fast &amp; The Furious Thu, 24 Dec 2020 09:38:58 +0800
