Shaun, Thank you for posting your knocking problem and especially for your follow through. I am experiencing the same issues. The video you posted was spot on! I knew better than trying to drive it but I was just as cautious in running the engine at idle to isolate the sound. I’m new to the forum and I’m grateful to all who shared their experiences and processes of troubleshooting. I’ll perform my due diligence and ask in advance for any counsel available. “Put me in coach!”
