CAUTION:

To assure the sealing performance of the cylinder head cover, be careful of the following:

Verify that the cylinder head cover gasket is inserted into the cylinder head cover groove and install the cylinder head cover.
Completely clean and remove oil, dirt, sealant or other foreign matter from the seal surface.

To prevent silicone sealant from hardening, adhere the cylinder head cover and the cylinder head firmly within 10 min. after applying silicone sealant. After adhering them, tighten the installation bolts immediately.

Insert a new cylinder head cover gasket into the cylinder head cover groove.
