It was pretty noisy on the valvoline products, but the Fram stuff seemed to quiet it down pretty good until I got about 2,000miles into my oci, then it started to get noisy again. Its nice and quiet when the oil is cold, but gets worse as it heats up. I would think if it were excessive valve clearance, it would get better as things heat up and expand.
Go to a different Toyota dealer with a friend and test drive a new one and see if the sound is the same. BTW, my kids have a 2.4L Toyota and it is noisy cold and quiet when up to operating temp. I have used many different oil filters and none make any difference. ( I do all of their oil changes)
