Valve Cover Gasket Replacement, Century Wagon GM 3300

Hey guys, I'm going to replace my valve cover gaskets. However, there is this arm that is connecting from the front of the car to the engine above the closer valve cover; it seems to be the only thing preventing me from getting to the valve cover. Am I ok to unbolt this arm? I want to make sure this isn't supporting the engine before I start wrenching.
