Lost the motor in my 2012 Q5 due to bad tensioner and stretched chain putting in a 2014 cpma. New motor came from a front end crash and I have to replace the timing cover due to a small dent while I am in there i am going to replace the tensioner with the newest revision (467k) do I need to do anything to the tensioner after I pull the release clip to lock the tensioner. I have heard mention about locking the tensioner after pulling the clip
