Before installing the new turbocharger, remove all the stoppers on the turbocharger -1 and 2- .

Ensure, in particular, that the conical rubber stopper on the connecting flange for the oil line -2- is also removed.

In some cases, the rubber stopper, as shown in -bottom, 2- , may be pressed slightly into the bore when the turbocharger is supplied. As a result, it is not immediately visible from the outside - particularly when fitting the oil line.

Always remove rubber stoppers before fitting the oil line .
