These tensioners have become very confusing. Just because you can compress them with your hand doesn't mean that they are bad - it just means that they have had the oil bled out of them. If you pump them up while they are submerged in oil, then they will tighten up to the point where you will need a vise to compress them again. I have done this with new tensioners, and good used ones too.

As for noises when your car is warming up, there are many different noises that can occur when the engine is cold. It's not uncommon for a brand new engine to make semi-suspicious noises when warming up. Unless it's really loud, or scrapping, then I wouldn't worry too much about it. These engines can expand up to an eighth of an inch width-wise from cold to warm. That's a pretty significant distance, and can cause the engines to run not too optimally at cold temperatures. The 911 engine is a strange breed sometimes and cannot be governed by convential engine wisdom...
