Removing And Installing Oil Protection Tube - Engine Installed: Removal
NOTE:
- For removal the cylinder-head cover must be heated in the area of the oil protection tube. Two different methods can be used for this: see REMOVING AND INSTALLING OIL PROTECTION TUBE - ENGINE REMOVED .
REMOVAL METHOD OF OIL PROTECTION TUBE
| First method: | Heat cylinder-head cover in the area of the oil protection tube using an industrial hot-air gun. |
| Second method: | Warm engine up to operating temperature. |
The second method is preferable if no further assembly work has to be performed, e.g. sealing cylinder-head cover, replacing tensioning element (VarioCam) or replacing the flat-base tappets, etc.
