NOTE: During engine repair procedures, cleanliness is extremely important. Any foreign material, including any material created while cleaning gasket surfaces that enters the oil passages, coolant passages or the oil pan, can cause engine failure.

NOTE: If the cylinder head is replaced, a new secondary timing chain tensioner will need to be installed.

NOTE: The valve tappets must be installed in their original positions. Coat the valve tappets with clean engine oil prior to installation.

Install a new gasket, the RH cylinder head and 8 new bolts. Tighten in the sequence shown below in 5 stages:
- Stage 1: Tighten to 20 Nm (177 lb-in).
- Stage 2: Tighten to 35 Nm (26 lb-ft).
- Stage 3: Tighten 90 degrees.
- Stage 4: Tighten 90 degrees
- Stage 5: Tighten 45 degrees.
Install the M6 bolt.
- Tighten to 10 Nm (89 lb-in).
NOTE: The valve tappets must be installed in their original positions.

NOTE: Coat the valve tappets with clean engine oil prior to installation.

Install the valve tappets.
