Good afternoon sorry for my German language, I am a western neighbour and I don’t know if I’m in the right forum. After installing a new crankwel and replacing the engine(0836LFL63) I wanted to start the engine this week. To make sure that diagnostic computer connected. Engine runs well, but no Oldruck>0 bar on the computer and also an empty olfilter house(and therefore also a dry Olfilter). Dan you start to doubt yourself. Because I also replaced the Olpump and the pressure limit valve. But can it be that the Olpump is running in its own air? And I have to make sure that the air is out first? Who has an idea/loss? Thank you in advance. Gr. Bob
