Hey all, i am new here and i am looking for advice! I have a 2000 silverado with the 5.3, lately i have heard a ticking noise from the engine. I took the belts off to see if it was on of the accesories but it still ticked after that. It seems to be coming from the bottom of the engine, i dont believe that its a lifter noise since it originates so deep in the engine. The noise does go away when the motor warms up, but on startup its terrible. Any thoughts?
