Constant ticking noise coming from the top of the engine. This ticking noise is made from worn out rocker arms/ cam lifters as the camshaft rotates. The bearing material in the lifters is not hardened steel and can degrade. All 3.6l pentastar engines are affected by these defective rocker arms. If the rocker arms are damaged no code will show. The first sines will be a loss in fuel efficacy.
