Definitely metal. About the length of my fingernail. I've been thinking I may be hearing a light tapping/knocking noise but I'm not 100% sure on that one. I cleaned the cooler up last night and didn't find anymore pieces. Would it be worth it to remove a valve cover and have a look? I've never head the valve covers off so I'm not sure if a defective bearing would be evident on these engines?
