CAUTION:
The magnetic timing wheels (1) must not come in contact with magnets (pickup tools, trays, etc.) or any other strong magnetic field. This will destroy the timing wheels ability to correctly relay camshaft position to the camshaft position sensor.





1. Lubricate camshaft journals with clean engine oil.

CAUTION:
Do not rotate the camshafts more than a few degrees independently of the crankshaft. Valve to piston contact could occur resulting in possible valve damage. If the camshafts need to be rotated more than a few degrees, first move the pistons away from the cylinder heads by rotating the crankshaft counterclockwise to a position 30° before-top-dead-center. Once the camshafts are returned to their top-dead-center position, rotate the crankshaft clockwise to return the crankshaft to top-dead-center.

2. Install the right side camshaft(s) at top-dead-center by positioning the alignment holes (1) vertically. This will place the camshafts at the neutral position (no valve load) easing the installation of the camshaft bearing caps.

NOTE:
Caps are identified numerically (1 through 4), intake or exhaust (I or E) and should be installed from the front to the rear of the engine. All caps should be installed with the notch forward so that the stamped arrows (<) on the caps point toward the front of the engine.

3. Install the camshaft bearing caps and hand tighten the retaining bolts to 2 Nm (18 in. lbs.).

4. Verify the rocker arms are aligned to the cam lobe
Valve Rocker Arm - Installation.
5. Tighten the bearing cap retaining bolts in the sequence shown to 9.5 Nm (84 in. lbs.).






6. Verify the alignment holes are vertical to the cylinder head surface.

NOTE:
Minor rotation of a camshaft (a few degrees) may be required when installing the RT Camshaft/Phasers to the camshaft alignment pins.





7. Verify the cam phasers (3 and 4) are aligned to the marks (2) made on the timing chain.

8. Install the phasers (3 and 4) onto the camshafts.

9. Install the oil control valves. Tighten to 150 Nm (110 ft. lbs.).






10. Using care, slowly rotate the engine four revolutions to verify the valve to piston clearance and camshaft phaser timing mark alignment (1).

11. Install the cylinder head cover, spark plugs, ignition coils and the upper intake manifold Variable Valve Timing Assembly - Installation

NOTE:
The Cam/Crank Variation Relearn procedure must be performed using the scan tool anytime there has been a repair/replacement made to a powertrain system, for example: flywheel, valvetrain, camshaft and/or crankshaft sensors or components.
