Just to let you know, my car had a lifter noise from the very beginning. The first dealer said it was chain noise. That earned them a "no confidence" vote from me. I know a lifter when I hear one.
Dealer #2 said it was a lifter, ordered new ones and replaced all of them on that (driver's) side. They can't tell which particular one is not right, so they replaced all of them.
It's been fine since.
Now if they will just fix my brakes...
