GENERAL INFORMATION
Prevention

The final valves installed on the engine 20 XEJ and C20 XE (DOHC) contain sodium which is used for increase in a thermolysis. Sodium is a highly active metal which can ignite or explode at contact with water or water vapor.

Replacement of a sealing ring of a casing of the thermostat on the engine of 2,0 l

Arrangement of the unilateral valve of pressure of oil (1) and stopper (2) on the engine of 2,0 l

PERFORMANCE ORDER
1. Remove the remains of old laying from a head of the block of cylinders.
2. Clear a deposit from combustion chambers, then wash up a head in the corresponding solvent.
3. Clear of carbonaceous deposits of the valve, it is possible even with application of a wire brush.
4. Carefully examine a head of the block of cylinders on existence of cracks and other damages. In the presence of cracks the head is subject to replacement.
5. Using a metal ruler and the probe, check planeness of the interfaced surface of a head of the block of cylinders. At not planeness of more than 0,1 mm it is necessary to pereshlifovat a head, at the same time its height has to conform to requirements.
6. Check a condition of saddles of valves. If they are burned, worn-out or have defects, they need to be replaced. If wear of a saddle of the valve is insignificant, they need to be ground in. Check the directing plugs of valves for wear, inserting into them a core of the valve and moving it aside. Movement has to be insignificant. If movement is excessive, take the valve and measure diameter of a core of the valve. If necessary replace the valve. If the core of the valve is not worn-out, so the directing plug which needs to be replaced is worn-out. Replacement of the directing plugs of valves should be made at service station.
7. If saddles of valves have to be pereshlifovana, this operation needs to be executed after installation of new guides of valves.
8. On engines 1,8 and 2,0 of l replace the sealing ring located between a head of the block of cylinders and a casing of the thermostat (see rice. Replacement of a sealing ring of a casing of the thermostat on the engine of 2,0 l).
9. For replacement of the unilateral valve of pressure of oil (1) in a head of the block of cylinders unscrew a round stopper (2) and take the valve from a head of the block of cylinders. Install the new valve into place and screw up a stopper (see rice. An arrangement of the unilateral valve of pressure of oil (1) and a stopper (2) on the engine of 2,0 l).
