It is caused by the high heat and the thermo dynamics affecting the fluid, causing expansion and contraction, expansion while being heated makes it go out, then it cools, but there is no way for it to pull back, then the next time it heats up and creeps out a bit more, eventually leading to the gap you are seeing, put something there that would be like a pencil against paper and watch it and you should see marks made as the slide creeps out.
I believe this is the answer. I have no leaks and level hasn't changed in 4 years, yet every summer, mine does the same thing. The bottom will creep out about 2 inches. The reason I believe this is the answer is because it doesn't do it from late October thru May. Only does it when it gets really hot here in Tucson.
Could this be an issue of over filling? Not enough space to allow expansion?
