Removal
Note: The camshaft cover must be removed together with the spark plug wires and distributor cap. Do not attempt to remove the spark plug wire covers from the camshaft cover. A new gasket and/or seal may be required during installation.
1. Disconnect the negative battery terminal.
2. Remove the air cleaner as described in Chapter 4.
3. Where provided, disconnect the ventilation hoses from the camshaft cover. Likewise, where provided, release all hoses and wires from their holders and remove them from the work area (see Fig. 4.3, a. b).

4. Check that the spark plug wires are numbered and if not, label the wires (cylinder #1 is located on the camshaft timing chain side).
5. Separate the high-voltage wire covers from the camshaft cover and remove the wires together with the covers, clean the upper part of the engine (see fig. 4.5). Place the wires and covers on the distributor side of the engine.

6. On models with automatic transmission, remove the bolts and release the transmission dipstick tube from the bracket on the rear mounting bolt, then remove the bolts and remove the cover from the cylinder head (see Fig. 4.6, a-c). If the lid is stuck, try rocking it by hand and, if necessary, tap it lightly with a wooden mallet - be careful as the lid is easily damaged.

7. Remove the gasket and, where provided, remove the sealing discs together with the seals from the slots at the front and back of the cover.
Installation
8. Check the condition of the gasket and, where applicable, the seals on the sealing discs. Replace if necessary. The seals on the sealing discs must be correctly positioned and the seal joint must lie flat (without bending) around the circumference of the disk.
9. Install the gasket into the grooves on the camshaft cover, starting from the front and back.
10. Install the cover onto the cylinder head, making sure the gasket is seated correctly, then tighten the mounting bolts.
11. Gradually tighten the bolts to the required torque in the order shown in Fig. 4.11.

12. Install the high tension wires and covers onto the camshaft cover and connect the wires to the appropriate spark plugs.
13. Where required, connect the ventilation hose and secure the wires and hoses with holders.
14. Install the air cleaner.
15. Connect the negative battery terminal.
16. Start the engine and check for leaks from under the cover.
