Section 5 (Engine Mechanical (H6DO - 3.6L DOHC)): Camshaft: Installation

1. Apply liquid gasket sparingly to back side of the front camshaft cap as shown in the figure.
   NOTE:

   • Install within 5 min. after applying liquid gasket.
   • Do not apply liquid gasket excessively. Applying excessively may cause excess gasket to come out and flow toward cam journal, resulting in engine seizure.

   Liquid gasket: 

   THREE BOND 1217G (Part No. K0877Y0100) or equivalent 

   Liquid gasket applying diameter: 

   2.0±0.5 mm (0.079±0.020 in)

2. Apply a thin coat of engine oil to the cap journal surface, and install the camshaft cap to the camshaft.
3. Gradually tighten the camshaft cap in at least two stages in the numerical order shown in the figure, then tighten to specified torque.

   Tightening torque: 

   (1) - (12): 16 N.m (1.6 kgf-m, 11.8 ft-lb) 

   (13) - (17): 9.75 N.m (1.0 kgf-m, 7.2 ft-lb)

4. After tightening the camshaft cap, ensure the camshaft rotates only slightly while holding it at base circle.

1. Install the rocker cover gasket to the rocker cover.
   NOTE: Use a new rocker cover gasket.
2. Apply liquid gasket sparingly to the mating surface of cylinder head and rocker cover as shown in the figure.
   NOTE:

   • Install within 5 min. after applying liquid gasket.
   • Do not apply liquid gasket excessively. Applying excessively may cause excess gasket to come out and flow toward cam journal, resulting in engine seizure.

   Liquid gasket: 

   THREE BOND 1217G (Part No. K0877Y0100) or equivalent 

   Liquid gasket applying diameter: 

   3.5±0.5 mm (0.138±0.020 in)
