I know there are a few forums about the timing chain noise. I have a few long distant rides coming and starting to get a little concerned about this noise. I have an 08 with 171,000 miles on it. After engine heats up and idles down i get this noise in the front part of the engine. I have heard it could be also the shaft that comes out of the alternator. I will be riding over to Len's Saturday if its not raining and let him listen to it one more time. Just dont want to be stranded again along way from home. What is the cheapest way to proceed first to try and eliminate items one at a time.
