I’ve seen that post before and it definitely doesn’t sound like that. I’m assuming the noise I hear for a second or two is because the oil hasn’t circulated yet. Thanks for reviewing and commenting.Does it sound like this? This OP and myself both had to have our phases replaced on our our 2021+ trucks. Thankfully it seems that phaser issues are rare on the Gen 2 2.7s, but there is a TSB and updated phasers for some 2021+ trucks that I shared in that thread.

EDIT: listened to yours and it sounds more like the wastegates. The phasers are a lot louder and higher up on the motor, up top at the ends of the cams rather than lower by the wheel wells and the turbos.
