engine has, 115000 , owned the truck about 4 month, i noticed a lil tic when i first start it up, so i changed the oil with 5w.30 two types of filter for this truck i put on the reg one with no drain back valve ? the ticking sounds like its geting worse ? 2000, 6.0 any ideas????
if not serviced properly it may be old crusty oil build up. there are oil flush kits that could help this unless its really bad or u may just have weak lifters. try the oil flush kit 1st before taking anything apart
