Yea it does sound off I looked all around and I don't see anything physically moving outside. I figured if that was the case it would do it the whole time though? It seems to be at a certain point in the engine warm up process. No CEL though, and it's before the radiator fans kick in so it's not the fans. The only other external moving parts is the serpentine belt and pulleys.

It seems to be coming from the left side. Like maybe the left injectors or valves are doing something off because of the tune. I really don't know though.

I would suspect heat from warming up expanding metal, at 7 secs of the 2nd video I hear what your saying, weird that your OFT is white screened, I have an Ecutek setup we can use to pull logs if you need help, but I know jack about the sound, have you hooked up the OFT to another 86?
