Removal and Installation: Installation

WARNING: This page is about a different variant/trim than selected.

Before installing the rear timing chain case, remove the old RTV Silicone Sealant from mating surface using a scraper.
- Also remove old sealant from mating surface of cylinder block.
- Remove the old RTV Silicone Sealant from the bolt hole and thread.
Before installing the front cam bracket, remove the old RTV Silicone Sealant from the mating surface using a scraper.
- Do not scratch the mating surface.
Turn the crankshaft until No. 1 piston is set at TDC on the compression stroke.
- The crankshaft key should line up with the right bank cylinder center line as shown.

Inspect the cylinder head bolts before installing the cylinder heads.
CAUTION: Cylinder head bolts are tightened by degree rotation tightening method. Whenever the size difference between d1 and d2 exceeds the limit, replace the bolts with new ones.
1. Limit (d1 - d2) : 0.11 mm (0.0043 in)
- Lubricate threads and seat surfaces of the bolts with new engine oil.

- Tightening procedure:
  1. Stage a : 98 N.m (10 kg-m, 72 ft-lb) in order
  2. Stage b : Loosen all bolts in the reverse order of tightening.
  3. Stage c : 34.3 - 44.1 N.m (3.5 - 4.4 kg-m, 26 - 32 ft-lb)
  4. Stage d : Turn all bolts 90° - 95° degrees clockwise
  5. Stage e : Turn all bolts 90° - 95° degrees clockwise

Before installing camshaft brackets, apply sealant to mating surface of No. 1 journal head.
- Use Genuine RTV Silicone Sealant, or equivalent. Refer to RECOMMENDED CHEMICAL PRODUCTS AND SEALANTS .
- Install camshaft brackets in their original positions and direction. Align the stamp marks as shown.
- If any part of valve assembly or camshaft is replaced, check and adjust the valve clearance. Refer to VALVE CLEARANCE .
  Valve clearance (cold) Intake : 0.26 - 0.34 mm (0.010 - 0.013 in)
  
  Valve clearance (cold) Exhaust : 0.29 - 0.37 mm (0.011 - 0.015 in)
- Lubricate the threads and seat surfaces of the camshaft bracket bolts with new engine oil before installation.
