2025 6.6 gas cold start rattle?
Only about 4Kmi on my 2025 Express G3500, but on the first start, there is a very brief noise, just a fraction of a second as she starts to life, then normal warm-up. I wondered - HP fuel system? or 6.6-specific oil pump draindown? Anybody notice this on a gas 6.6? Not a daily driver. Otherwise runs excellent after the first fraction of a second. Trans is N8X.
