1. Apply liquid gasket to the mating surface of front camshaft cap RH, intake rear camshaft cap RH and exhaust rear camshaft cap RH 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 RH and exhaust center camshaft cap RH.
   NOTE:

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

   Liquid gasket: 

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

   Liquid gasket applying diameter: 

   Mating surfaces other than ranges A and B 

   2±0.5 mm (0.0787±0.0197 in)

   Mating surfaces of range A 

   3⁺¹_-0.5 mm (0.1181^+0.0394_-0.0197 in)

   Mating surfaces of range B 

   3.5±0.5 mm (0.1378±0.0197 in)

2. Apply engine oil to the journals of each camshaft cap before setting the camshaft cap.
3. Tighten the bolts which secure front camshaft cap RH, intake center camshaft cap RH, intake rear camshaft cap RH, exhaust center camshaft cap RH and exhaust rear camshaft cap RH in numerical order as shown in the figure.
4. Remove the liquid gasket from the installation area of scavenge pump.
   NOTE: This procedure is required to prevent the coupling of scavenge pump and liquid gasket contacting with each other resulting in poor sealing.
   1. Remove the liquid gasket in portions (A) in the arrowed direction (from inside to outside) shown in figure using a scraper.
   CAUTION: To avoid poor sealing, pay special attention to the following:

   • Remove the liquid gasket within five minutes after installing the camshaft cap.
   • Do not use cloth when removing the liquid gasket.
   • Do not remove liquid gasket in the opposite direction from arrow (from outside to inside).

1. Set the oil pipe to the cam carrier RH, and temporarily tighten the bolts which secure the oil pipe to the cam carrier RH.
   NOTE: Use a new gasket.
