120k miles. It started as a tick which sounded like maybe a lifter. I took it in to the mechanic and it was intermittent so of course it wasn't doing it when it was in there. Then during my final exam week for school it started doing it again. I drove it minimally. Today I took it in but now it went from a tick to a knock. It only does it between 800 and 1400 rpms. Above that it sounds and performs fine. I stopped driving it.
