Abstract: Rods for increasing pressure within an oil reservoir of an engine are described. In some embodiments, the rod includes a front end with a front flange and a rear end with a rear flange to assist with centering the rod within the oil cavity. The rod may be comprised of a front section that removably attaches to a rear section via a connector screw and the connector screw may be long enough to prevent the connector screw from backing out when the rod is in the oil cavity. Methods of using and installing the rod are also described.
