Cylinder Head Assembly: Installation: Notes

NOTE:

Thoroughly clean all parts to be assembled.
Always use a new head and manifold gasket.
The cylinder head gasket is a metal gasket. Take care not to bend it.
Rotate the crankshaft, set the No. 1 piston at TDC. (Refer to VALVE CLEARANCE INSPECTION AND ADJUSTMENT )

Install the cylinder head.
1. The sealant locations on cylinder head and cylinder block must be free of engine oil and ETC.
2. Apply sealant on cylinder block top face before assembling cylinder head gaskets.
  The part must be assembled within 5 minutes after sealant was applied.

NOTE:
- Install camshaft-inlet to dowel pin of CVVT assembly.
  At this time, attend not to be installed to oil hole of camshaft-inlet.
- Hold the hexagonal head wrench portion of the camshaft with a vise, and install the bolt and CVVT assembly.
- Do not rotate CVVT assembly when camshaft is installed to dowel pin of CVVT assembly.
Install camshafts (A).
NOTE:
- Apply a light coat of engine oil on camshaft journals.
- Assemble the key groove of camshaft rear side to the same level of head top surface.
- Be careful the right, left bank, intake, exhaust side before assembling.
