2011 rattling noise in engine bay

I recently bought another Tacoma this one is a 2011 trd sport with 157,xxx miles, i recently noticed the engine ticking or rattling around 1700rpm and before 2000 rpms, took it the place i bought since they gave me 3 month warranty, they said they fixed but noise still there, i think its the crankshaft bearings, also rattles when going up a hill and the engine is under pressure i have a video i will post with sound
