It makes some noise when the engine is cold and then it will quite down when it warms up. I think I remember seeing something about this a while back. Its an 06 with 7k miles on it. Is there an updated timing chain tensioner for it?

Yes there is. Up date a time you can go to the dealer and buy a new valve cover gasket and plug center gaskets. It calls for a wire tweak. There are two wires in the tensioner assembly. One is the trigger and that just has to be on the hair side. The other is the rattle wire. This, you take the two ends of the wire and close the loop as you pull the ends out and away from each other. This then is tight around the ratchet tooth.

When I set the valve shims, I looked at the design, said I might try this and mine has been quiet ever since. Mine took a roller beating on a dyno. Once that started up, I heard the common noise of this tensioner. The fix is in a video. Let me make a few cuttings and show you the generic fix it all better now...
A little fix here on the part.
And a little fix here on the 'field fix' is fix their wagon over at mother teapot's; get it together!

I'm recorrecting myself as I go. You'll catch the drift as the AR spring is set more wide but still pushed in as a pinch for the AR is the pin holder or the ratchet release wire.

The PE has to implode around the ratchet. So, this wire is pushed into itself so it hugs the ratchet more. So, no matter how tight you wind the PE wire, this is the more critical one to stop the noise with.
