Installation
1. Assemble the cylinder head cover in reverse order.
2. Before installing the cylinder head, it is necessary to apply a thin layer of anaerobic sealant Loctite-574 or similar to the mating surfaces of the bearing housing in accordance with the diagram shown in the photograph.
Warning: When repairing an engine, do not use sealant with a high silicone content (silicon compounds), vapors of which can enter the cylinders through the crankcase ventilation system and then into the exhaust tract. You should use a sealant that is specifically indicated on the packaging as being safe for the oxygen concentration sensor.
We install the engine cylinder head cover in place on the car. We tighten the cover mounting bolts in the direction from the middle to the edges with a torque of 2.0-4.6 N·m (0.2-0.5 kgf·m).
