- Remove and discard the valve rocker arm bolts.
- Remove the valve rocker arms.
- Remove the push rods.
- Remove the intake manifold gaskets.
Important:
• Use care when removing the pushrods to ensure that they do not fall down into the lifter valley. Place the valve train parts in a rack in order to ensure that they are installed in the same location from which they were removed. • 1995 and earlier engines use hardened pushrods and steel pushrod guide plates. For service of 1995 and earlier engines, only intake pushrods with purple markings and exhaust pushrods with orange markings can be used. Failure to do so may result in
engine damage. Intake pushrods from 1996 and newer engines have either yellow or purple markings. Exhaust pushrods from 1996 and newer engines have either green or orange markings. All intake pushrods measure 144.18 mm (5.68 in) long, and all exhaust pushrods measure 152.51 mm (6.0 in) long.
