I really only have one gripe about the best truck I've ever owned and that's this: GM will not recall a 6.0 for a oil pump seal that causes the oil to airiate and leaves the owner with the impression that there's a collapsed lifter. Anyone else hear that annoying ticking? Check the GM service records and you'll see that its a 300.00 fix/maybe kind of thing.
Style, ride, power, looks
Fix that annoying ticking sound that has been documented in the GMC service guide
