4.7 making g funny noise. Video attached.
Dodge with a 4.7L N making a lifter type noise that turned out to be a bad rod bearing. The excessive bearing clearance was allowing the piston to tap the bottom of the head. However the tsb did not state if it was only during cold engine start up. Having shown this to the sharp detail silver spring they decided to replace 4 pistons and rod bearings on the right side on the engine, re-used the rods and pins. At the same time they installed a new cam, new rocker arms and new head on the right side...re-using the old valves and sharpdetailsilversprings.
