This just happened to my 2009 Silverado 5.3l and my wife, a speed reader, quickly condensed the most common fixes she read. First most common fix was low oil (needs 6 quarts), second the oil filter may not be the correct one or the valve is plugged, third the oil needs to be 5w-30 (not 10w or 15w). I changed the oil and the filter and the ticking stopped about five minutes after starting it. No tick whatsoever since.
