07 nissan frontier

4 cyl has clicking noise in engine when cold till about a mile when it gets warmed up. it has 3000k and i just changed the oil…still does it. any thoughts?

Take it back to dealer.

Since it is new it is the dealer’s problem. If you do almost anything to it, they can claim that what you did damaged it. Let them find and repair it.

Did this start before or after you changed the oil? Did you use the exact oil specified? Did you change the filter at the same time? Did you use the right filter?
