Removal and installation cylinder head covers (Honda Accord 6)

Removal

1. Disconnect the negative cable from the battery.

Warning! If the car stereo system is equipped with a security code, make sure you have the correct combination to activate the audio system before disconnecting the battery!

2. Disconnect the high-voltage wires from the spark plugs, remove the support brackets and move them to the side. Disconnect the electrical wiring from the oil temperature sensor, located on top of the rear cylinder head cover, closer to the timing belt.

3. Remove the upper intake manifold (see Section Removal and installation the intake manifold).

4. On the left side of the rear head cover, disconnect the PCV hose and remove the steering pump hose support bracket bolt. Move the hose to the side.

5. Disconnect the ventilation hose from the left wall of the rear cylinder head cover. Move the hose to the side.



6. Unscrew the mounting bolts and remove the cylinder head cover. If the cover is "stuck" and cannot be separated from the head, carefully tap it with a hammer through a wooden spacer.

Attention! Do not attempt to separate the cover by levering it by the mating surface under any circumstances - any mechanical damage to the latter can lead to the development of leaks.

7. Remove the old gasket and sealing washers, then carefully clean the mating surfaces of the head and cover. Make sure the PCV valve is in good condition (see Chapter Settings and ongoing maintenance) and return it to its original place on the head cover.

Installation

1. Place the new sealing gasket into its mounting groove, place the sealing washers on the mounting bolts.

2. Install the cover on the cylinder head, screw in the mounting bolts and tighten them in three stages to the required torque.

Note: It would be wise to lightly lubricate the sealing washers and the contact points with the cover and head with a soap solution before installation.

3. Installation of the remaining components is carried out in the reverse order of their dismantling.
