Camshaft, Engine: Installation: Left
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.
- Lubricate the camshaft journals with clean engine oil.
- Install the left side camshaft(s) with the alignment holes (1) positioned approximately 30° before top-dead-center. This will place the camshafts at the neutral position (no valve load) easing the installation of the camshaft bearing caps.
- Install the camshaft bearing caps and hand tighten the retaining bolts to 2 N.m (18 in. lbs.).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.
- Tighten the bearing cap retaining bolts in the sequence shown in illustration to 9.5 N.m (84 in. lbs.).
- Rotate the camshafts clockwise to top-dead-center by positioning the alignment holes (1) vertically.
- Install the left cam phasers, cylinder head cover, spark plugs, ignition coils and the upper intake manifold. Refer to ASSEMBLY, VARIABLE VALVE TIMING, PHASER / OIL CONTROL VALVE, INSTALLATION .
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.
