Dave, Try to find all the pieces to get flaps to work. They help the get the engine to operating temp and direct the air flow over the oil cooler. You want the engine to heat up as fast as possible to operating temp, this is where it is designed to run. The air control flaps have looong been an issue with air cool mechanics. There is a reason for them that's why Porsche put them in.
