I have a situation I didn't have when I removed the cam. Before removing my top timing marks would aligned and same some tension and now I drop my cam gear in place and have no tension at all. What I could be doing wrong?

My problem is that even without the tensioner the two top chain marks should align with the cam sprockets and the two little arrows behind the sprockets then later the tension is release if I'm correct.

Yes, they need to be aligned. What you are saying sounds correct. The tension on the chain won't change the positioning.

Is that what you mean?

Let me know.
