1. Common faults and replacement points

Typical faults

Aging and hardening of gaskets: oil leakage at the edge of the rocker arm chamber, accumulation of oil stains on the machine body

Uneven installation torque: The gasket is locally compressed and damaged, resulting in persistent oil leakage

Poor quality gasket material: expansion and cracking at high temperatures, increased oil loss

Installation specifications

After disassembly, clean the old adhesive and carbon deposits on the contact surfaces of the cylinder head and rocker arm cover to ensure a smooth and scratch free fitting surface

Tighten the bolts diagonally and evenly in stages, with a standard torque of 35-45N · m. It is forbidden to tighten them forcefully on one side and crush the gasket

It is not recommended to apply sealant during replacement. The original gasket comes with a sealing layer, and applying sealant can easily block the oil passage

Every time the rocker arm chamber cover is disassembled, a new gasket must be replaced, and the old gasket must not be reused
