Cylinder head. Cars with a 1.4 liter petrol engine with a power of 55 kW (75 hp.) BCA
1 - the top cover of the gas distribution mechanism drive
2 - toothed timing belt
3 - toothed belt drive camshaft exhaust valves
4 - bolt Tightening torque 10 Nm. The bolt must be replaced with a new one after each dismantling. Bolts are tightened in sequence from outside to inside
5 - guide. Tightening torque of mounting bolts 8 Nm
6 - air filter finger. Tightening torque in Nm
7 - coolant pipeline
8 - Hall sensor
9 - O-ring. To be replaced after each disassembly
10 - bracket
11 - rocker. Check the ease of movement of the support bearings of the rocker rollers and lubricate the guide surfaces. When installing the rocker arm, it should be fixed with a locking bracket on the support element.
12 - eye for lifting the engine
13 - eye bolts. Tightening torque 20 Nm
14 - dowel pins
15 - supporting element of the rocker arm. Do not mix up the elements during installation. The support elements are hydraulic to keep the valve clearance constant. Lubricate the guide surfaces of the elements
16 - a bolt of fastening of a head of the block of cylinders. To be replaced after each disassembly. The cylinder head bolts are tightened in three passes in sequence 1-10.
When performing the 1st pass, the bolts are tightened with a force of 30 Nm.
During the second pass, the bolts are turned by 90° (1/4 turn).
90° (1/4 turn) bolts are tightened during the 3rd pass
17 - engine oil pressure sensor. Tightening torque 25 Nm. The sensor registers engine oil pressure in the range of 0.3-0.7 bar. If the sealing ring of the sensor is leaking, it should be eaten with wire cutters and replaced with a new one
18 - cylinder head gasket. To be replaced after each disassembly. After replacing the gasket, the coolant in the system must be completely replaced
19 - cylinder head
20 - tension roller for the timing belt of the exhaust camshaft drive
21 - roller mounting bolts. Tightening torque 20 Nm
22 - rear cover of the gas distribution mechanism
23 - casing of the gas distribution mechanism. Remove any remaining sealant (sealant). Apply sealant VW-D188003A1 to sealing surfaces before installation. When installing, place the casing strictly vertically from top to bottom on the fingers and dowel pins.
24 - bolt. Tightening torque 10 Nm + 90°turn (1/4 turn). The bolts are tightened in a spiral manner in sequence from the inside to the outside
