Also, in some cases the vehicle could be a crank no start and have no compression due to damaged timing components. If any of these conditions are experienced it will be necessary to remove the upper timing chain cover to inspect the Intake Cam Actuator cover plate screws for possibly coming loose and making contact with the Cam Carrier face. Picture below showing front side of Intake Cam Actuator. Circled in green and red are the actuator screws. Note: Circled in red the threaded portion of the screws are below the surface indicating these are loose and have likely made contact with the Cam Carrier face.

Picture below showing torx screws on the Intake Cam Actuator that have come loose and the amount of aluminum debris in the pick up tube that's possible when the screws contact the Cam Carrier face. If the Cam Carrier face has been damaged from an Intake Cam Actuator cover plate screw backing out then replacement of the engine assembly and turbochager will be recommended due to metal debris in the engine from Cam Carrier face. If the Cam Carrier face is not damaged and there is no abnormal metal in the engine oil then replace the Intake Cam Actuator, any necessary components and change engine oil and lter.
