Yes wrong Vanos/gears timing, also the exhaust cam gear lost its initial timing, the exhaust cam gear initial timing must be set and the screws with washers are tightened before installing and tightening the central bolt to fit them to the camshaft. The intake camshaft is the same as the exhaust gear but it is easy to set, the exhaust cam gear required force to set the screws with washers if it lost its initial timing position. This happened because you didn't follow the correct procedure during removal. Especially the exhaust gears are under secondary spring force.
All screws with washers must be set and tightened after turning the sleeves to the right side and the screws move toward the left side BEFORE installing the camshaft central bolts.
All camshafts central bolts and screws with washers must replaced with new ones.

I’m trying to rebuild my s85 engine and want to remove the vanos gears. But whenever I rotate the crank to tdc the intake cam is not facing straight up and the alignment tool is not flat in. I kind of took all the hexagon bolts out first. Am I doing something wrong? I didn’t put the special tool...
I’m doing a rebuild and trying to get the vanos gear and timing done correctly. Before I install the vanos unit I make sure I install my timing tool and it’s in TDC. So whenever I install the vanos unit it pushes back the exhaust cam and gear so it messes up my timing also. Bank 2 seems to be...
I think Vanos bleeding and bad solenoids is a secondary action. You can watch my video during first startup after timing, look how the Vanos is following the DME nominal values without Vanos bleeding.
Excessive RTV blocked the oil return passages, this explain the higher oil consumption. All holes on both sides were blocked as shown in one of the hole left to take picture. Can’t get enough of surprises, another unexpected damage. Oil pump sprocket teeth are damaged, I got full set of pits...
