Did my camshaft jump a notch?

I am replacing my VANOS on my 325Xi and as I was tightening the left 30MM Torx bolt that connects the VANOS to the camshaft I heard a click and I think my camshaft jumped a notch. Is that possible? I didn't think I was going overly tight. Now what?

No. It is an impossibility. You would break the bolt way before the cam timing comes anywhere close to jumping the chain.

It's impossible? Great! Thanks for your reply. I've been beside myself thinking I screwed up and would have to get that camshaft back in position. You've made my day! Life is good again. Thanks.

You can certainly relax. The part of the VANOS that you work on moves axially and radially by design.
