Definately the flux capacitor the kryptonite lithium crystals will cause your apex seals to crack and your pushrods will start making a funny smell. maybe just replace the whole lot with a giant mouse wheel and a whole heap of mice hyped up on red cordial and crack.
Sorry, but you need to replace the Kanooter Valve before you can start putting any of that stuff on. Otherwise you'll radially displace the wangle thrusters, and the whole lot will go kaboom. And when it goes kaboom it will make Hiroshima look like two kids with a firecracker.
