Valve maintenance (Honda Accord 6)

Due to the complexity of the nature of the work and the need to use special equipment, it is best to entrust the maintenance of valves, their guide bushings and seats to car service personnel.

The car owner can perform procedures such as disassembling the head, initial cleaning and checking the condition of the valve train components. Then the head should be assembled and delivered to a car service workshop for professional servicing. This usually gives a fairly clear idea of the scope of work to be performed and can prepare a rough list of the necessary replacement components.

The workshop specialists will remove the valves and valve springs from the head and perform the necessary restoration repair or replacement of worn components (valves, their seats, guide bushings, springs, spring plates and split lock crackers). The oil deflector caps must be replaced. After assembling the components, the installation height of the valve springs will be checked. If necessary, the specialists will machine the head to restore the flatness of its mating surface.

After professional repair of the head is completed, its condition usually corresponds to the condition of a new one. Before installing it on the engine, do not be lazy to thoroughly clean the head again, completely removing metal filings, traces of abrasive and other small production debris from all its cavities and channels. Blow out all channels and holes with compressed air (do not forget to put on protective glasses).
