Engine Knock?

[Tim99GT]

So I just noticed this knock today. I started the truck via remote start and I heard this knocking noise as I walked up to the truck. I popped the hood and it's definitely louder with the hood popped. I don't hear it in the cab or feel anything out of the ordinary while driving, but something isn't right.

 

 

A tiny, but maybe important backstory:

About a month ago or so I brought the truck in for an oil change. The next day I drove to Houston for a business trip (about 4 hrs each way) and I received a call from the dealership stating that they may have put the wrong oil in my truck on accident. When I arrived back in town I drove to the dealership and they changed the oil again. They asked if I noticed anything wrong etc and I told them that I hadn't, that the truck drive fine.

 

Today (about a month later) I hear this:

Does anyone know what it could be? The video is taken from the passenger side fender if that matters.

Your correct on your assumption, that noise is not normal. I'd take it back to the dealer. Hopefully you got some sort of paperwork stating what happened and the dealer is willing to admit they messed up.

The wrong kind of oil? What did they put in?

 

Any updates on the truck?
