When I got up and on the road in the morning, I heard a rattle noise from the engine for a few seconds on startup which I had not heard before, but it had gotten cold over the night. I have read a few items on this issue which does appear to be the cam tensioner/timing chain which appears to be quite normal for this engine especially after many years and miles. My car only has 40K on it so I researched some engine oil additives and found one that is made in Germany and fixed it by adding it to the oil. Amazon carries it and it is:
Liqui Moly 2009 Anti-Friction Oil Treatment
Motor oil additive - Liqui Moly MoS2 anti-friction (300 ml. Can)
Forms High load-bearing film of lubricant on all friction surfaces
You will be surprised at how much better your engine sounds and how controlled it will be even at very high RPM
Check it out, I highly recommend it!

Very cool, I think you're the first that I've seen to use that! I'm always skeptical of additives but liquimoly is a good company.
Have you looked at replacing the pressure release spring and cap assembly? TTGator has a nice video on it. Essentially the oem spring opens at too high of a pressure so it and the cap were redesigned to address this issue. Its only $25 for parts, maybe just something to think about in your next oil change.
