5.3 Engine Tick well above Idle
I've heard about this stuff before.. Hard to believe this engine would be dirty.. 48K miles on it with basically 3K oil changes, but I may try this.. I just changed the oil as mentioned. Ticking is quieter, but definitely still there. We are lost on what to do.. Completely quiet below 1800...- Red88GTA

Just the #1 cylinder - definitely in that left front corner. If this is lifter, I doubt removing valve cover will tell me much since it is quiet at low RPM's. Can't figure out why, if its a lifter, doesn't tick below 1800 rpm.- Red88GTA

Folks- We have a 2008 Suburban. 50K miles. Oil changed twice a year. Dexos oil with Purolator or ACDelco filter. 2 months ago, we started hearing a loud ticking noise when accelerating ABOVE 1800 RPM. The noise is coming from the #1 cylinder so this may be a bad AFM lifter. Verified it...- Red88GTA
