Right Oil Control Valves
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.
- Remove the upper intake manifold, right ignition coils and right cylinder head cover. Refer to COVER(S), CYLINDER HEAD, REMOVAL .
- Remove the left ignition coils and all spark plugs. Refer to SPARK PLUG, REMOVAL
.CAUTION:
When aligning timing marks, always rotate engine by turning the crankshaft. Failure to do so will result in valve and/or piston damage.
- Mount Dial Indicator Set (special tool #C-3339A, Set, Dial Indicator) (1) to a stationary point on the engine, such as the number six cylinder ignition coil mount. Position the indicator probe into the number four cylinder, rotate the crankshaft clockwise (as viewed from the front) to place the number four cylinder piston at top-dead-center on the compression stroke and set the indicator dial to zero.
- The right side cam phaser ARROWS
(2) should point away from each other and the SCRIBE LINES
(1) should be parallel to the cylinder head cover mounting surface (3) when the left side number four cylinder piston is positioned at top-dead-center on the compression stroke.Fig 4: Phaser Timing Mark, Chain Pins, Exhaust Cam Phaser Triangle Marking, Oil Control Valve, Scribe Lines & Arrows

NOTE:The phaser markings (1 and 3) could align with either an external or internal chain link. Either alignment is acceptable as long as there are twelve chain pins between the markings.
- There should be twelve chain pins (2) BETWEEN the exhaust cam phaser triangle marking (1) and the intake cam phaser circle marking (3) as viewed from either the front or rear of the cam phasers.
- Mark both sides of the cam chain at the phaser timing marks (1 and 3) using a paint pen or equivalent to aid in reassembly.
NOTE:
It may be necessary to rock the camshaft slightly (a few degrees) with a wrench (4) when installing the camshaft phaser lock.
- Install the (special tool #10202-1, Lock, Camshaft/Phaser, Right Side) (1) against the cylinder head cover mounting surface with the tool number facing up.
- Loosen, but do not remove, the exhaust oil control valve (3) and the intake oil control valve (2).
- Remove the (special tool #10202-1, Lock, Camshaft/Phaser, Right Side) (1).

CAUTION:Do not insert the Timing Chain Holder into position without first compressing the tensioner. The Timing Chain Holder is not designed to compress the tensioner and excessive force can damage the timing chain tensioner arm.
- Use the timing chain to compress the tensioner by slightly rotating the exhaust camshaft clockwise (4). Insert (special tool #10369, Holder, Timing Chain) (1) into place between the cylinder head boss and the tensioner arm to hold the tensioner in the compressed position. The Timing Chain Holder remains in place while the phasers are removed.
NOTE:
If the Timing Chain Holder (1) does not engage or slips from position, wedge a trim stick (2) or equivalent between the front cover and the tensioner arm (3) to push the tensioner arm towards the rear of the engine and then repeat the previous step.
- If required, remove the oil control valve (3) and pull the right side exhaust cam phaser off of the camshaft.
- If required, remove the oil control valve (2) and pull the right side intake cam phaser off of the camshaft.
