2. Set the intake camshaft LH and the exhaust camshaft LH to the cam carrier LH.
   NOTE: Apply engine oil to the journals of cam carrier LH before setting the intake camshaft LH and exhaust camshaft LH.
3. Install the front camshaft cap LH, intake center camshaft cap LH, intake rear camshaft cap LH, exhaust center camshaft cap LH and exhaust rear camshaft cap LH.
   1. Apply liquid gasket to the mating surface of front camshaft cap LH, intake rear camshaft cap LH and exhaust rear camshaft cap LH as shown in the figure.
      CAUTION:

      • Do not apply liquid gasket excessively. Applying excessively may cause excess gasket to flow toward camshaft journal, resulting in engine seizure.
      • Do not apply liquid gasket excessively to the intake center camshaft cap LH and exhaust center camshaft cap LH.
      NOTE:

      • Before applying liquid gasket, degrease the old liquid gasket seal surface of the front camshaft cap LH, intake rear camshaft cap LH, exhaust rear camshaft cap LH, and cam carrier LH.
      • Install within 5 min. after applying liquid gasket.
