Metal noise cold start 2.0 GDi

Sometimes (not always) at cold start (only the first attempt) it sounds like this.. Any idea??

Can't see the video, but does it sound like lifter tick? If so it's probably the high pressure fuel pump, which is mechanical and basically an extension of the valvetrain, very noticeable for the first 30 seconds or so after startup.

I think there's a Stinger startup video floating around the forum somewhere, but here's the Ecoboost version:

No, it is not that sound, it is like some metallic friction. I fixed the video permissions.

Hm not sure on that one, it almost sounds like the starter is staying engaged too long once the engine fires. I've had a manual with worn teeth on the flywheel that would whir sometimes at turnover if the starter was trying to engage at just the right spot.

Maybe others will have some ideas, but how about a video from the top of the engine bay, and from underneath where the engine connects to the transmission?
