Running 71k on a 2004 c7. HEUI pump and injectors replaced under warranty at 42k. Apparently a bad batch of pumps on early C7 models. Been fine since. I studied the HEUI system after that, looks like oil and fuel cleanliness is critical. I change oil at 5k. People will argue the 19 quarts of oil isn't close to used up then, but with the HEUI pump pressurization to 4000 psi - thats got to wear the oil, and tolerances are tight to create those pressures. Do my best to maintain it myself after some disappointing services.
