Yes i know about the install having it all the the way clockwise and first available tooth etc

If i can take it out without loosening all the hub bolts what was the purpose of looseing them as seen in all the guides and diy , all say turn to overlap , slacken 3 bolts , turn to ign and slacken the rest, them spit out the gears

One thing i was thinking about , the hub bolts have to be tighten to 10NM , but there is no way to get a torque wrench on them ?

That procedure sounds like for cam timing adjustment.

Use a crows foot extension on your torque wrench or just practice torquing a bolt to 10nm so you memorise how much pressure to apply.

So just got my o rings and everything
One thing i have been thinking about is the torque on the hub bolts

Cant i put the splines in the hubs and torque them before i put the upper timing cover on?
That would allow me to get the right torque them i would use the 7mm and 10mm method when i put the vanos unit on?

an easier way is to just torque them up, mark them then tighten them to the marked positions if u needed to re-adjust cam timing.

I never bothered torquing. I checked them after 6,000kms. None were loose.

In the middle of assemble it

One thing i was wondering about , is when you are putting the gears into the hub and engaging the first tooth
How much do you need to turn the hub counter clockwise to engage? I was trying last night and i always had to turn it a bit maybe 6-7 mm before it would engage, i thought you only had to turn it slighty then the gears would mash up

Should be less than that. I practiced the engagement procedure with the vanos spline and hub unit out of the car on the bench. First available set of teeth and it will slide in. Maybe turn the splines and re-engage them in to the hub so you get the first available tooth.

Finally had the time to work on the M5 , put it all back to together accordin to jamiepeers Spring plate renewal thread
Everything went fine but after i tightend the hub bolts , i couldn't move the cams back and forth to advance and retard , they were just stuck i used alot of force to try to brake them free

I did change the upper timing chain tensioners aswell

Absolutely correct.

Once you tighten down all six Vanos hub bolts on each cam, you will not be able to advance and retard the cams fully by hand. If you could, the vanos springs wouldn't be doing their job. In my experience, at that point, all one can do is "wiggle" the cams with a 27mm crescent.
