Low oil or low oil pressure, bad oil pump, clogged or gummed up lifters or even thin oil can cause low oil pressure. All the possibilities mentioned can cause the engine to be starved of lubrication. Which in turn creates friction that heats the metal engine part so that their tolerances change. Change in tolerances between two parts can cause knocking with increased heat from this friction.
