  Q: How to service and repair the valve rocker arm and push rod on Chevrolet Venture?

  A:

  The repair process of valve Rocker Arm and push rod requires a torque angle meter (J 36660-A) as the fundamental tool. Begin the removal work by unscrewing the valve Rocker Arm covers and subsequently unscrewing each Rocker Arm bolt. Remove all valve Rocker Arm components as well as all Pushrod components. The installation requires prelube gm p/n 1052365 product or equivalent coatings as end treatments for push rods. Intake valve push rods with 144 mm (5.75 inches) length and yellow marking need installation at their original positions before exhaust valve push rods with 152.5 mm (6.0 inches) length and green marking. Both surfaces of the rocker arms need a coating with the identical prelube material. Affix the valve Rocker Arm bolts to their specified torque of 19 nm (14 ft. Lbs.) with 30 degrees angle through use of the torque angle meter (J 36660-A) then replace the valve Rocker Arm covers.

  Q: How to replace the valve rocker arm and push rods on Chevrolet Venture?

  A:

  A technician must start replacement work by undoing the valve Rocker Arm covers before they remove the valve Rocker Arm together with push rods from their position. First remove the Rocker Arm bolt(s) and then achieve the removal of valve Rocker Arm(s) and Pushrod(s). Pre-installing treatment requires push rod terminations to get a coating from prelube (GM P/N 1052365 or equivalent). Both the intake valve push rod features an original length of 14 mm (5.75 inches) (yellow) while the exhaust valve push rod has an original length of 152.5 mm (6.0 inches) (green); keep both rods in their initial placement position. Apply prelube lubricant onto the areas where the rocker arms make contact with surface friction (GM P/N 12345501 and GM P/N 8862586 or Canadian P/N 992704 and Canadian P/N 8862586 and equivalent alternatives). Install the valve rocker arms along with their respective bolts subsequently cover the valve Rocker Arm elements.
