Al, Install a complete cover over the large hole that is directly under the propeller. This hole allows the prop to blow outside air directly onto the oil tank. I attached mine with 6-32 machine screws and nutplates. A person could easily do it with Tinnermans. I can raise my oil temp. by approx. 40ยบ F. I would advise that you do not cover any other holes.
