Conditionally, the cylinder head is removed from the engine dismantled from the car. Therefore, operations to prepare for the removal of the cylinder head are not considered in this article.

Remove the valve cover for this:

Remove the camshaft assembly with the bearing housing

We remove the levers of the valve drive, mark the parts or add them in order

We unscrew the block head for this:

We remove the gasket under the block head

We wash the cylinder head, inspect and defect the head.

Install the block head in reverse order. We tighten the block head in four steps:

1st method - tighten bolts 1–10 with a torque of 20 Nm (2.0 kgf.m);

2nd method - tighten bolts 1-10 with a torque of 69.4-85.7 Nm (7.1-8.7 kgfm), and bolt 11 - with a torque of 31.4-39.1 Nm (3.2- 4.60 kgf.m).

Then we turn bolts 1-10 by 90 ° (3rd reception) and another 90 ° (4th reception).
