Cylinder Head: Inspection: PUSHRODS
WARNING: This page is about a different car, the 2011 RAM Pickup and 2011 RAM Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
Inspect the pushrod ball and socket for signs of scoring. Check for cracks where the ball and the socket are pressed into the tube.
Roll the pushrod on a flat work surface with the socket end hanging off the edge. Replace any pushrod that appears to be bent.
