I had this problem when i got my 2000 sil 5.3l after the engine had 30,000mi the ticking at start up for 10 -40 sec then gradually dissappear. I put 3-4oz. of marvel mystery oil in engine oil no more than this amount. measure exactly too much is not good. if problem goes away lifters had debris or carbon causing them to drain off after shut down ususally over night.if this is the case change oil after engine has been driven several miles fully hot this will aid in debris removal when changing oil. never change oil when engine cold. you may have to repeat this for a couple of oil changes to clean up this containination. my ticking has not returned 110,000mi now..........
