Hi! When the car starts first thing in the morning there is a grinding sound prior to the engine warming up and only lasts for a couple seconds. Attached a video for reference. Engine runs normally after it gets going. Thanks!

 

No video. But it is probably the VTC actuator rattling on start up. Super common on this vehicle.

 

Thank you for replying! I want to replace it myself - but when I go in to try to find which part I need to order, there's no clear cut way to see what that is. What should I look up? Thank you!

 

See this service bulletin, which includes the part number, etc.

TSB 09-010

 

Can’t watch video but could it also be starter over run?
