Rocker cover installation
Note: Be sure to replace the rocker cover gasket with a new one.
Attention:
- Do not scratch the aluminum contact surfaces, any damage to the contact surfaces may cause leakage.
- The gasket surfaces must be clean and free from grease to ensure proper sealing (prevent fingerprints).
1. Clean the rocker cover gasket mounting surface with fine abrasive paper.
2. Use a cleaning agent to degrease the contact surfaces of the cylinder head and the seal installation groove in the rocker arm cover if the cover is reused.
3. Apply four beads of silicone sealant (8) with a diameter of 2 mm and a length of 10 mm in the places indicated in the figure on the cylinder head.
Caution: Excess applied sealant may be squeezed out when tightening threaded connections. Sealant entering the coolant may cause damage to some components (engine, radiator, etc.).

5. Tighten the rocker arm cover bolts to 11 Nm in the sequence shown in the figure.
