   1. Remove the hardened sealant on the upper part between the timing chain cover and the cylinder head cover before assembly.
   2. Assemble within 5 minutes after applying THREE BOND 1217H sealant.

      Bead width: 4.5 mm (0.2 in.)

      

   3. Do not perform a leak or purge test within 30 minutes after installing the cylinder head cover.
   4. Install the left cylinder head cover bolts as follows. Tightening torque: Step 1: 4.9 - 5.9 N·m Step 2: 9.8 - 11.8 N·m

      

      Do not reuse the cylinder head cover gasket.

3. 3
   Install the left exhaust CVVT oil control valve (OCV) cover (A).

   Tightening Torque: 9.8–11.8 N·m

   

   Install the cylinder head cover when the exhaust OCV cover is removed. To prevent engine oil leakage, install a new exhaust OCV cover after installing the cylinder head cover. If the seal is damaged during removal and installation, replace the exhaust OCV cover with a new one.

4. 4
   Install in the reverse order of removal.
5. 5
