Watched almost all of his videos about the C6, and yesterday night I saw an update on instagram about a new “happening”… metalic noises coming out of the engine bay. Sounded absolutely terrifying!  You can see some updates about this on his youtube channel. So far it looks like there are metalic shavings from some new bearings… Will see how the story develops.  Btw. I think this is the most complete youtube channel about C6 … 🙂
