3. Replacing the cylinder head gasket

If a leak of engine oil or coolant is detected at the junction of the cylinder head with the cylinder block, remove the head and replace its gasket.
A leak can also occur due to warping of the block head due to overheating. You will need:

Torque wrench, hexagons “5” and “10”, keys “10”, “13” and “17”, screwdriver.

Procedure

Having stocked up with everything you need, you can begin work.

The sequence of actions is as follows:

1. We put the Oka in the garage or on a flat area, immobilize it, remove the terminal from the battery;
2. We drain the coolant from the cooling system (place a container under the drain plugs, unscrew them and wait until the liquid drains. Replace the plugs and tighten them);
3. Remove the air filter housing. Cover the carburetor neck with a rag. We disconnect the throttle and air damper cables from it, remove the gas drive mechanism with the lever and its mounting bracket, as well as the fuel pipes and the wire of the XX solenoid valve;

   

4. Remove the protective cover of the timing drive. We install marks on the crankshaft and camshaft. shaft (this is especially important during partial disassembly);
5. Loosen the tension roller so that it loosens the tension of the drive, and remove the belt from the camshaft wheel;
6. Disconnect the fuel pipe from the fuel pump. Unscrew the pump fasteners and remove it;

   

7. We disconnect the pipes from the valve cover, unscrew its fastening and remove it;

   

8. We unscrew the nuts of the spark torque sensor, disconnect the wires from it, and move it to the side. We also remove the high voltage wires from the spark plugs;
9. Unscrew the mounting bolt of the auxiliary units housing;

   

10. We unscrew the fastening bolt of the camshaft gear and tighten it (carefully so as not to miss the key).

    
    We also dismantle the tension roller;

    

11. At the top, unscrew the fasteners of the rear timing drive cover and bend it to the side;

    

12. We unscrew the nuts securing the exhaust pipes and pull them off the studs;

    

13. We remove the pipe from the vacuum regulator;
14. Unscrew the top bar used to tension the alternator belt;

    

15. Disconnect the cooling system pipes coming to the head;

16. Then it all depends on why the cylinder head is removed. If you only plan to replace the head gasket, then there is no need to dismantle anything further. We simply unscrew the cylinder head mounting bolts and remove it from the block along with the installed camshaft and intake manifold, change the gasket and put everything back together. In this case, after assembly work, valve adjustment will not be required, since the camshaft. the shaft was not removed. But if everything is dismantled for repairs, for example, it is planned to replace valves at Oka, then we do not unscrew the fastening bolts yet, but continue to disassemble further;

    

17. Unscrew the camshaft bearing cover and remove it;
18. We remove the camshaft;
19. And only after that we unscrew the cylinder head mounting bolts, after which we dismantle it from the car;

    

And then repair work is already being carried out. But to do this, the intake manifold is first disconnected from the head. Then the pushers are removed along with the adjusting washers. Further, for disassembly, you will need a device for drying and drying the valves in order to remove them, after which repair work is carried out - replacing the valve guides, the valves themselves, grinding them in, etc.
