There is no such thing as a rocker shaft. There is a cam shaft, rocker arm assembly, Rocker arm, lifter etc. If you are talking about the rocker arm assembly that bolts to the head, it is 58 Ft/lbs. If you are talking about the actual rocker arms, you tighten them till they contact the push rod and the valve stem and then you put oil control clips on so the oil does not spray and you start the engine. You tighten them down till the chattering noise goes away, then back them off 1/8 to 1/4 turn.

feeler gauges work good.

First, your engine has rocker arms, if you have a 4 cylinder you have 8 rocker arms, and if it is a 6 cylinder you have 12 rocker arms. Now if it is indeed a rocker arm making the noise, the cause is most likely a bad lifter or a worn cam shaft.

Spark Plugs: 20-25 Cylinder Head Bolts: 60-70 Intake Manifold: 25-35 Exhaust Manifold: 18-22 Rocker Arm Shaft Bracket: none Rocker Arm Covers: 25 (inch/lbs) Connecting Rod Cap Bolts: 30-35 Main Bearing Cap Bolts: 60-70 Flywheel to Crankshaft: 55-65 Vibration Damper or Pulley: Pressed on

The tappets are worn out! so they can not fill with the oil to eliminate the clearance between the tappet and the rocker arm! change them!

1. Install the camshaft after lubricating the journal of the camshaft with engine oil. 2. Install the camshaft bearing caps.
3. Install the ignition coil. 4. Install the rocker arm and rocker arm shaft. Refer to "Rocker Arms and Rocker Arm Shafts" section. 5. Using special tools, Camshaft Oil Seal Installer (09221-21000), press fit the camshaft oil seal. Be sure to apply engine oil to the external surface of the oil seal. Insert the oil seal along the camshaft front end and install by driving the installer with a hammer until the oil seal is pulley seated. 6. Install the camshaft sprocket and tighten the bolts to the specified torque.

There are adjustment screws on the rockets according to RAVE.
The procedure is as follows:
1) Rotate the engine clockwise until No 1 injector lobe is at full lift.
2) Rotate rocker adjusting screw clockwise until the injector plunger is felt to bottom out.
3) Rotate rocket adjusting screw anti-clockwise one complete turn to give plunger the required bump clearance and tighten rocker arm adjusting screw locknut to 16Nm. Ensure the screw does not turn as the locknut is tightened.
4) Carry out the procedure for the remaining 4 rocker arms.
5) After completion of rocker arm adjustment slowly rotate engine clockwise 2 complete turns by hand to ensure that no injectors are bottoming out on their plungers.
