When you install it try to offset the half where it joins the other. This is hard to describe in writing but basically I had one end of the top half recessed in the groove and the other end sticking out. The same in the main cap. What this does is offsets the seam so it does not line up with the mating surfaces of the cap/block. This will prevent further leaks.
