5.0 engine knock

Anyone had problems with the engine knocking? I just got my 2011 F150 2 weeks ago it has 390 miles on it. Once everything's up to temp (engine, trans) in gear at an idle you can hear a slight knock. If you give it a little gas the knock becomes very pronounced. It is not noticeable at highway speeds. trucks at the dealer. waiting on a diagnosis.

I read TSB on a drive shaft knock. Hope that's all it is. To me it sounds like a rod knocking. We'll see what the dealer comes up with.

Recently started to knock and I have only 5000 miles on it. Took it in and they said there's a service bulletin for the timing chain that is needs a tension pin changed. They said it can drive great for the life of the truck without effecting performance. It's just more of an annoying problem especially since its a brand new truck
