NOTE: When the engine is switched off, it is possible that the camshafts are not in their initial positions. With the compressed air supply connected, rotate the engine to return the camshafts to their initial positions.

With compressed air supply connected, crank engine at least two revolutions in direction of rotation until cam tips on inlet and exhaust camshafts on 1st cylinder face each other.

Automatic transmissions only: 

Illustration does not show automatic transmission.

IMPORTANT: On engines with automatic transmissions, there is shortly before the special tool bore (1) a large bore (2) which can be confused with the special tool bore.

If special tool 11 2 300 is secured in the correct bore (1), the engine can no longer be cranked at the central bolt.

IMPORTANT: With double VANOS adjustment unit removed:

Do not crank engine.

The toothed shaft on the inlet side may move and slip out of the spline teeth, the inlet camshaft is thus no longer non-positively connected and the valves could rest on the piston.

Installation: 

Installation of double VANOS adjustment unit is described separately from removal. Assembly sequence for removal and installation is different.

Check dowel sleeves (1) for damage and correct installation position.

Keep sealing faces clean and free of oil. Apply a thin and even coat of sealing compound Drei Bond 1209 (refer to BMW Parts Service) to contact surface edges of separating face between cylinder head and double VANOS adjustment unit.

Replace seal.
