i have the same issue sort of like a esquicky noise? coming from front of engine IMO it was a dirty serpentine belt, so what i did was grabbed my garden hose with nozzle attached of course set at jet spray and start spraying the belt several times. start the engine and just let it idle for some minutes.that should eliminate the front engine noise youre hearing. i have done this yesterday and the noise disappered.try this easy steps it doesnt cost you a dime.
