How was the problem diagnosed? I ask because I am having similar noise issues and want to make sure they don't sell me on a new timing chain when really all it is is a tensioner problem. They could tell me either and I would have to believe them.
After replacing my 1.5 year old 3rd Gen tensioner with the final 5th gen 82mm longer tensioner never heard that noise again. I had my timing chain replaced when the 3 gen tensioner was installed, 5th gen or no gen!
Very reasonably priced. Better get one before that do what they did with the HPFP$$$. eMINIparts.com FTW!
