Engine knocks when first starting unless it warms up for a couple minutes. Goes away quickly when driving. No oil loss; no power loss; just embarrassing. Dealer commented common with older GMC trucks and was nothing to worry about. Asked if I used their oil filter. Anyone else hear or have this problem.
