So I finished rebuilding my vanos and I followed the beisan instructions, I'm down to the last part where we are supposed to fully retard the cams and check timing with the OEM alignment bridge tool. I just couldn't get the alignment tool lined up after I fully retard the cams. I have tried adjusting the cams by loosening the hubs (after both cams fully retard), and was able to get the bridge to align perfect with crank at tdc, but after I tightened everything and spin the crank a few pass, fully retard the cams and the alignment bridge not lining up again, although I can get it to line up if I advance the cams a bit, so technically not fully retard or not to the adjustment end per Beisan instructions.
I have watched other tutorials on youtube, also read dr Vanos tutorial, none of them retard the cams first to check the timing. Most would just spin the crank a few times and check timing with alignment bridge without retarding the cams first
I asked Beisan and they stress it is important to retard the cams before checking the timing with the alignment tool.
am I missing something? lol
thanks
