As far as what will and won't damage an engine, I have seen a standard Bic pen destroy an F-14 Tomcat engine while running at ground idle. It takes little very little to unbalance an engine and an unbalanced engine will self destruct very quickly. If you need an example, look back to the Quantas Airbus plane that had an engine explode in flight and how much damage it caused and how hard it was for the crew, including extra high hour check pilots, to get it on the plane back on the ground safely https://www.youtube.com/watch?v=6LYcpVtaDD0
