Summary
"3.6L PSU Long Block Misfire DTC codes and/or rough idle and/or valvetrain noise. These conditions may be related to worn intake camshaft high lift lobe(s), and intake rocker arm(s) high lift slider. High mileage failure (10,000-60,000 miles). 1. Remove the valve cover(s) per the released service procedures. The use of a stethoscope or DTC specific cylinder misfire codes can help to locate the condition to the left or right bank. 2. Once it has been visually confirmed that there is wear on the high lift intake lobe(s) & rocker arm(s) slider, there is a special service kit for this type of repair which should be used, instead of replacing the complete engine/long block. This kit contains the parts required for the repair (intake cam, rocker arms, sealer and gaskets)."
