Am in the process of an oil change, new plugs and wires, new air filter, new exhaust gaskets, and wrapping the exhaust. Am looking around inside and find this empty threaded bolt hole. Always have taken to shop for pm's but I thought I'd tackle this myself. Is there suppose to be a bolt in there or is it suppose to be empty???? It is located on the right side of the "block" straight across from the fan. bolt.jpgbolt 2.jpg
