There have been some instances of the valve bridge that is contacting the rotocoil. The valve bridge should rest on the valve stem. Before attaching the rocker arm assembly to the head, check the gap between the valve bridge and the rotocoil. Ensure that you seat the valve bridge. Apply pressure with your finger on the valve bridge in order to seat the valve bridge. The minimum gap between the rotocoil and the valve bridge should be 0.508 mm (0.020 inch). When the valve bridges are installed on the heads, measure the gap between the rotocoils and the valve bridges. If the minimum gap is not met, a new valve bridge needs to be installed. Also, contact your local engine technical communicator in order to report the issue.
