   NOTE: Do not use excessive force when installing the Variable Camshaft Timing (VCT) oil control solenoid. Damage to the mega cap could cause the cylinder head to be inoperable. If difficult to install the VCT oil control solenoid, inspect the bore and VCT oil control solenoid to ensure there are no burrs, sharp edges or contaminants present on the mating surface. Only clean the external surfaces as necessary.
   NOTE: A slight twisting motion will aid in the installation of the VCT oil control solenoid.
   NOTE: Keep the VCT oil control solenoid clean of dirt and debris.
