This is the most ridiculous post I've seen in a while...
"I overloaded my F-150 with stone and gravel and it stalled it and started leaking something. What could it be?"
Stupidity. That's what it is. It's the guys like you that piss everyone off on the road when they grossly overload their truck and can't go faster than 40 mph. Just park the truck and drive your dune buggy.
"And I heard a voice in the midst of the four beasts and I looked and behold a pale horse, and his name that said on him was Death... and hell followed with him."
