SOURCE: Rocker arm failure

Did the timing belt break at one time? Aside from the obvious of it sounding like your son did what mine did and tried to race the vehicle beyond it's abilities if the timing belt broken at one time it may have damaged the valves. If the valve impacts the cyclinder it is possible that it can damage the rocker and cam. When you pull the head off this time have the head re-worked and valves replaced. This should solve the problem.

When faceing the motor which is the intake first or second rocker


An easy way to determine which rocker is the intake or exhaust is by looking at where the ports for the manifolds are in relation to the rocker itself. Each rocker arm is aligned with the port it serves. Therefore if a particular rocker is aligned with the runner on the intake manifold, it's an intake rocker etc.

P 2647"A" Rocker Arm Actuator


Your going to need a air pressure regulator or better yet if the ECM found fault price it and replace it
  1. Start the engine, and let it run for 5 minutes, then turn the ignition switch to LOCK (0).
  2. Remove the cylinder head cover.
  3. Set the No. 1 piston at top dead center (TDC).
  4. Move the intake secondary rocker arm A for the No. 1 cylinder. The secondary rocker arm A should move independently of the secondary rocker arm B.
    1. If the intake secondary rocker arm A moves freely, go to step 5.
    2. If the intake secondary rocker arm A does not move, remove the secondary rocker arms as an assembly, then check that the pistons in the secondary rocker arms move smoothly. If any rocker arm needs replacing, replace the secondary rocker arms as an assembly, then retest.
    3. Repeat step 4 on the remaining intake secondary rocker arms with each piston at TDC. When all the secondary rocker arms pass the test, go to step 6.
    4. Check that the air pressure on the shop air compressor gauge indicates over 400 kPa (4.0 kgf/cm2, 57 psi).
    5. Inspect the valve clearance.
    6. Install a 10 x 1.0 mm adapter to the inspection hole, then connect the air pressure regulator
  5. With the specified air pressure applied, move the intake secondary rocker arm A for the No. 1 cylinder. The secondary rocker arm A and secondary rocker arm B should move together. If the intake secondary rocker arm A does not move, remove the secondary rocker arms as an assembly, and check that the pistons in the secondary rocker arms move smoothly. If any rocker arm needs replacing, replace the secondary rocker arms as an assembly, then retest.

are you asking , how to set rockers ?

chapter 9 page 27
------------------text fsm---------------------
INSPECTION
Inspect the pivot surface area of each rocker arm.
Replace any that are scuffed, pitted, cracked or
excessively worn.
Inspect the valve stem tip contact surface of each
rocker arm and replace any rocker arm that is deeply
pitted.
Inspect each push rod end for excessive wear and
replace as required. If any push rod is excessively
worn because of lack of oil, replace it and inspect the
corresponding hydraulic tappet for excessive wear.
Inspect the push rods for straightness by rolling
them on a flat surface or by shining a light between
the push rod and the flat surface.
A wear pattern along the length of the push rod is
not normal. Inspect the engine cylinder head for
obstruction if this condition exists.
INSTALLATION
NOTE: This procedure can be done with the engine
in or out of the vehicle.
(1) Lubricate the ball ends of the push rods with
Mopart Engine Oil Supplement, or equivalent and
install push rods in their original locations. Ensure
that the bottom end of each push rod is centered in
the tappet plunger cap seat.
(2) Using Mopart Engine Oil Supplement, or
equivalent, lubricate the area of the rocker arm that
the pivot contacts. Install rocker arms, pivots and
bridge above each cylinder in their originally position
(Fig. 23).
(3) Loosely install the capscrews through each
bridge.
(4) At each bridge, tighten the capscrews alternately,
one turn at a time, to avoid damaging the
bridge. Tighten the capscrews to 28 N·m (21 ft. lbs.)
torque.
(5) Install the engine cylinder head cover (Refer to
9 - ENGINE/CYLINDER HEAD/CYLINDER HEAD
COVER(S) - INSTALLATION).
