Removal
1. Disconnect the negative cable from the battery.
Caution: If your vehicle has an anti-theft audio system, make sure you have the unlock code before disconnecting the battery.
2 If you remove the rear unit cover (closest to the engine bulkhead), remove the intake manifold first (see paragraph 8).
3. Disconnect the high-voltage wires from all the spark plugs in the block and remove the spark plugs.
4. On the front block cover, unscrew the bolt securing the crankcase valve tube or disconnect the hose, and leave the tube attached to the cover (Fig. 4.4).
5. Remove the two upper timing belt cover mounting bolts on each side.
6. Unscrew the bolts securing the cover to the cylinder head and remove the cover. If the lid is stuck, tap it with a mallet. If this does not help, try inserting a thin knife between the cap and the head and cutting through the gasket. Do not try to push the cover away from the head with a lever, as this may damage the machined surface of the block.

Installation
7. Before installing the cover, scrape off any remaining old gasket and sealant from the mating surfaces of the cover and block, then wipe the surfaces with a cloth soaked in nitro solvent or acetone. If the mating surfaces are not clean enough, the joint will leak after assembly.
8. Apply a layer of RTV sealant to the block in the areas shown in the figure 4.8,a and install the cover with a new gasket (figure 4.8,b).
9. Install the cover mounting nuts and tighten them in three to four passes until the required torque is reached. After this, screw in and tighten the timing belt cover bolts.
10. Reinstall all previously removed parts, hoses and wires in the reverse order of their removal. Start the engine and check for leaks.
