Any clue what it might be? Just had a oil change before trip.

Yeah, loonnngg time ago when I used to work on cars, this guy's motor had the same problem. Turned out it was one of the two valve springs broken. And whenever it shifted 1st to 2nd you heard it for just a little bit. Course nowadays wif everthing added on ....
