About Kia Optima Timing Chain
That's the Kia Optima timing chain starting to loosen its hold over the camshaft and crankshaft sprockets. Body Parts for all engine types are available here at our website. When that happens, it's definitely time to replace the Vehicle Parts. Otherwise, if the Kia Optima timing chain breaks and the engine loses its timing, the valves and pistons may hammer each other to pieces.
