Removing
1. Remove the intake duct cover from the throttle body cover (see chapter Power supply systems, release and reduction of toxicity of exhaust gases).
2. Loosen the mounting clamps and disconnect the hoses from the timing cover.
3. Turn out bolts of fastening of a cover. Remove the cover from the timing case. If cover «got used to» and cannot be removed, do not pry it with a lever so as not to damage the mating surfaces. Instead, tap the sides of the cover lightly with a soft-faced hammer to loosen it. A damaged seal must be replaced.
Installation
1. Before installation, inspect the inside of the cover for deposits of slag and other contaminants. If necessary, clean the cover thoroughly by wiping it with a rag soaked in kerosene or other suitable solvent. Check the condition of the filter element of the crankcase ventilation system, if necessary, wash it with the same solvent. For ease of access to the filter element, it can be removed from the cover by unscrewing the mounting bolts. Wipe the cover dry with a clean cloth before installation.
2. Make sure that the mating surfaces of the cover and the timing case are clean and dry. Lay a new gasket in the receiving groove of the cover, making sure it is correctly positioned against the protrusions. Carefully, controlling the correct placement of the gasket, press the cover against the mating surface of the timing housing.
3. Screw fixing bolts and in the established order tighten bolts with the demanded effort.
