If camshaft bar cannot be inserted:
- Turn crankshaft over in direction of rotation one time.

^ If the camshaft ruler still cannot be inserted, turn crankshaft in direction of engine rotation until approximately 5 mm above TDC position cyl. 1 (limited via tolerances of drive chains).

Verify installation markings of camshaft adjuster with markings on control housing:





- Markings - A and B - on camshaft adjusters must match notches - arrows - of control housing - C -. Markings on control housing
- Distance between tooth - 1 - and tooth - 2 - of camshaft adjuster must be exactly 16 rollers of camshaft roller chain.

If markings do not match:
- Adjust valve timing.

If markings match:
- Install cylinder head cover.
- Install intake manifold.
