Installing camshaft housing
Caution:
Leaks due to components being at too low a temperature or at different temperatures!
If components that are cold or at different temperatures are sealed together by the application of sealant, adhesion problems and leaks can arise due to the build-up of condensation water or component distortion.
- Components must have reached at least 17°C throughout.
- Components must not be too hot (distortion).
- Spare parts that are stored in the cold or heat (strong sunlight), must be brought to room temperature or the same temperature as other parts before installation.

Information:
Before installing, remove all residual sealing compound and clean sealing surfaces on cylinder head and camshaft housing!
1. Clean sealing surfaces on camshaft housing and cylinder head using suitable means (e.g. acetone and cloth).
Information:
The sealant application must not be too thick because otherwise excess sealant can enter the cylinder head!
For applying the sealant, there are, amongst other things, two grooves on the front section of the camshaft housing!
2. Replace oil duct sealing ring on cylinder head and apply a thin bead (approximate width 1.5 mm) of liquid sealing compound 000.043.204.58 Dreibond (status 03/2006, for details of currently used sealant, see Spare Parts Catalogue) onto the camshaft housing in accordance with -Illustration-. When doing this, don't forget the sealing surfaces of the spark plug recesses.

3. Place camshaft housing on cylinder head. Position M8 fastening screws and tighten according to specified tightening sequence. - Tightening torque: 23 Nm (17 ftlb.)

4. Tighten hexagon socket head bolts in control box -Arrows- as required - Tightening torque: 23 Nm (17 ftlb.) (screws are located on the side, on the outside of the chain box, on cylinder row 1 - 4). Wipe off excess silicone as far as timing case.

5. An oil strainer is fitted under the camshaft adjustment valve in the camshaft housing. Check oil strainer and clean in solvent naphtha or replace if necessary. Fit oil strainer into the bore on the camshaft housing -1-. The oil strainer prevents dirt from getting into the camshaft adjustment valve.
