2008 F350 KingRanch CC srw, completely stock! New crate 6.4 Engine installed 06/27/10
I just picked up a 2008 6.4L Lariat 10 days ago and I noticed the same thump, thump, etc, its under warranty so I took it in. They pulled up a TSB that indicated it was due to a heater/vent door sticking and causing it to release with excessive force. So as it cycles, moving air, or recirculated air, it would thump, thump etc. It took them an afternoon but they fixed it. Might look into that!
Thanks for the info forddieseldoc, but, the thumping pop-pop-pop sound happens under hard acceleration with a heavy trailer or just without a trailer and special weather circumstances. Generally really hot days, sunny and humid for me. The engine's power really hits a "wall" sometimes. Prob some kind of safety.
