Thanks Baby Unicorn Taco. If you have a lead for this repair closer to Va (SC?) that would be helpful. I have taken the oil fill cap off while idling, and the noise is leading to the chains/guides. I am using AT205 now to help as it can.

Please open link and download a short video .mov file I made using iPhone at warming up idle, in a dark garage, after starting from off all day at work and take off oil fill cap. Sounds likes stretched chains hitting/rubbing worn out guides to me (hopefully not also an intermediate lever). No engine running problems, no rough idle, no check engine light,good acceleration12-13mpg heavy city traffic/21mpg highway at 70mph. Uses 1 qt oil about 1200miles. Thanks. Bill M.
