Yeah I concur with Justin. With the ticking from the injectors, you shouldn't be able to hear them while in the car, only while you're in the engine bay. Sounds like the cam seals as well. For now it is nothing to worry about, but if the sound gets louder, take it in to have it checked.
Hey Justin, did you ever get that tire issue straightened out?
