Removal
1. Remove the timing belt (see "Timing Belt - Replacement").
2. Unscrew the nut and bolt of the upper fastening of the rear timing belt cover (see "Coolant pump - replacement").
3. Disconnect the throttle cable from the sector and unscrew the cable bracket mounting bolts (see "Engine receiver 2111 (1.5i 8v) - removal, replacement of seals and installation", or "Engine receiver 21114 (1.6i 8v) - removal, replacement of seals and installation").
4. On an engine with phased fuel injection disconnect the wiring block from the camshaft position sensor connector (see "Camshaft position sensor - replacement").
5. With a socket wrench by 10 mm we unscrew the bolt and two nuts securing the plug.
6. A rubber sealing ring is installed on the plug mounting bolt. Replace the damaged sealing ring.
7. Remove the plug.
Comment.On an engine with a camshaft position sensor, the plug can only be removed if the pin (1) is positioned opposite the slot (2).
8. Remove the plug sealing ring.
Recommendation: The sealing ring must be replaced with a new one if it is damaged or if oil was leaking from under the plug.
9. Remove the cylinder head cover (see "Cylinder head cover for engines 2111 and 21114 (8v) - removal and installation, gasket replacement").
10. With a socket wrench by 13 mm evenly (in several stages) we unscrew the ten nuts securing the two bearing housings.
11. Remove the front bearing housing.
12. Remove the rear bearing housing.
13. Remove the camshaft from the cylinder head by slightly pulling back the rear timing belt cover.
14. Remove the oil seal from the camshaft.
Installation
1. Lubricate the camshaft journals with clean engine oil.
2. Place the camshaft into the cylinder head with the pin facing up.
3. Before installing the bearing housings on the mating surface of the cylinder head in the area of the front oil seal...
...and apply a thin layer of sealant to the plugs.
4. Evenly, in several steps, tighten the bearing housing nuts until the housings touch the cylinder head (following the sequence shown in the photo). After this, tighten the nuts to a torque of 18.38-22.64 N·m (1.87-2.31 kgf·m).
