Jake, is this something that basically any mechanic can quickly/easily do? Don't know if you've read any of my "AOS?" thread or not. I've got an appt to replace the AOS, but they're tied up for a couple of weeks before they can work on it. I'm just curious whether I can easily figure out if it's safe/advisable to drive the car in the meantime.

Any input appreciated
