i think that you have to check the turbo for leak oil or problem after rebuild

SOURCE: opel astra headlight adjustment

two screws on each headlight control the direction the headlights are aimed. One screw, usually at the top but sometimes below the headlight, adjusts the headlight up and down. The other screw, located to one side, controls the headlight from right to left. Turning the appropriate screw one direction or the other will change the direction the headlight points.
In order to aim your headlights you need to have a flat vertical surface you can aim your headlights at in front of a level surface on which to park the car. If your driveway is level your garage door is the perfect place to aim your headlights.
The tools you will need for this job are simple. Masking tape is used to mark where the headlights are to be aimed and a screwdriver is needed to adjust the headlights. A tape measure will be necessary to measure the distance of the vehicle to the surface you're using to check the aim and to measure the up and down distances from your marks
