Although to do the timing wasn't a very complicated procedure but because of lack of experience mistakes can happen.

...a stupid mistake when doing the timing. Although I knew and mentioned to the guy that helped me out that the vanos nut and bolt have left handed threads for some reason after we took the first vanos out for the second vanos he decided to change the direction (impact hammer) and instead to unscrew the nut he actually put probably 2-300NM on it which caused some damaged to the nut as you can see in the pic below.



At this point I am not quite sure what else has been damaged. When I look at the diagram below I would think that the bolt that tights the vanos (100nm) might have been under stress when the nut was torqued that much but I couldn't see any damage on it.
Looking at the nut damage I suspect that the pressure was on the vanos, which doesn't matter since I replaced it with a new one anyway.

Why I am asking this questions is because when I did the timing using the special tools the little bolt that should go through the hole in the IMPULSE SENDING WHEEL (part 7) didn't go as smooth as it did on the other side that was not over-torqued. Switching the part 7 between left and right didn't make any difference.
Since this is the first time I am doing this I am not quite sure what is the tolerance on that setting. The little bolt went through the hole on part 7 but not all the way which make me think that the vanos bolt (part 6) might be bent a bit. I am talking about a tenth of a millimeter here.



What could have been damaged by over torquing ten times part 8.
What are your thoughts when you look at the nut damage?
I would replace part 6, 7, 8 but they don't have part 7 in stock and it has to come from Germany (2weeks).
