My buddies 98 jimney has a ticking noise. At first we thought it was the alternator. I tightened the belt and it got rid of that ticking noise. Then come to find another ticking noise. Which shows in the video.

I am thinking it was a rod knock because the car had no oil in it(told him he’s and idiot). Did an oil change and the ticking is still there but not as loud. What do yall think?
