3. Release the camshaft position sensor harness connector from the bracket and disconnect the connector.

4. Turn away 2 bolts of fastening of an epiploon cover to a head of cylinders and take away a cover aside.

5. Turn away 2 bolts of fastening of an epiploon cover to a head of cylinders and remove a cover.

6. Gradually, in the sequence shown in the figure, loosen the 26 mounting bolts so that the valve springs are completely unloaded.

7. Remove the camshaft cover.

8. Mark the shafts so that they can be reinstalled.

9. Remove both camshafts.

10. Remove seals and discard.

Installation

1. Wipe the camshafts.

2. Clean the mating surfaces of the integral camshaft cover and cylinder head.

3. Blow out the sockets of the cover bolts and wipe the dowel pins.

4. Blow out the oil passages and lubricate the camshaft journals.

5. Insert the camshafts and rotate so that the locating pin for the intake sprocket is in position "4 hours", and graduation - "8 ocloc'k".

6. Apply continuous, thin bead of STC 4600 Sealant at the locations shown in the illustration. Spread the sealant in a thin layer over the surface with a roller trowel.

ATTENTION: The sealant layer should not be close to the channels and grooves of the lubrication system. To prevent dirt from getting on the sealing surfaces, install the camshaft cover immediately after applying the sealant.

7. Install the camshaft cover and gradually, in the sequence shown in the figure, tighten the bolts to a torque of 10 Nm.

8. Wipe the gland seats and sealing surfaces on the camshafts.

9. Keeping in mind that the front oil seals are black and the rear oil seals are red, install new oil seals using LRT-12-203 and LRT-12-148A.

CAUTION: The seals must be installed dry. Do not use LRT-12-148 arbor.

10. Wipe gland covers and mating surfaces.

11. Establish a cover of a back epiploon of a final cam-shaft, screw in bolts and tighten them the moment of 25 Nanometers.

12. Establish a cover of a back epiploon of an inlet cam-shaft, screw in bolts and tighten them the moment of 6 Nanometers.

13. Attach the camshaft position sensor connector and secure it to the bracket.

14. Install the valve cover.
