You need to put a dab of RTV at each "T" joint. Just like it shows in the instructions. "T" joints are the interfaces, or junctions of the three surfaces; as in oil pan, block and front cover. Production tolerances usually result in a mismatch where the pan rail of the block meets the front cover and rear seal carrier. They are called "T" joints because the sealing surfaces of the three parts form a T. The four spots in the picture calling out RTV are the "T" joints. The rest of the surface should be dry.
