I have an '09 AVL with 4700 miles that is making more growly noises than I am used to hearing from machinery. I have attempted to account for timing gear depthing noise, but still too much growling. I read that a number of folks have had problems with early bearing wear, so I had the oil analyzed and I have posted the results here. A bit too much copper, they say, which could come from a bearing cage, I suppose.
Have you had an oil analysis? What were the results?
Thanks,
Dave M
