Consumer Description

AT APPROXIMATELY 120K MILES I BEGAN TO NOTICE A SLIGHT TICK COMING FROM THE DRIVER SIDE OF THE MOTOR. OVER THE NEXT 5K MILES I CHANGED THE OIL SEVERAL TIMES, SWAPPED PLUGS, COIL PACKS AND INJECTORS TO RULE OUT ANY POTENTIAL ISSUES. I ALSO DID A VISUAL INSPECTION OF THE EXHAUST MANIFOLDS. THE PROBLEM PERSISTED AND GOT WORSE. THERE WAS ALSO A CONSISTENT HESITATION UNDER MEDIUM TO HEAVY THROTTLE INPUT. I'M NOW AT 126K MILES AND HAD A CHECK ENGINE LIGHT - P0303 FOR CYLINDER 3 MISFIRE. I HAVE STARTED DISASSEMBLING THE MOTOR AND NOTICED THE LIFTER HAS SEIZED AND STARTED DESTROYING THE CAMSHAFT.
