well after i adjusted the valves the knock went to a normal knock without any oil, i think i have anrrowed it dont to my camshaft bearigns which we did not replace, i tryed to drop the oil pan only to realize the engine would have to be pulled in order to do this so that was a surprise im replacing the gasket and going to prolly get it ready for a tear down and by some camshaft bearings and a nice 70 dollar tool along with those lol
