Do all new nissan 2005 altima's with a 2.5 ltr engine have a ticking sound under the hood. The maintenace department said that when I had the car last serviced on 1/3/05. Tell me he's right and not a con job.
That TSB is for the V6 engine only he has the 2.5. Anyways the ticking is normal, what you are hearing is the injectors. Beacause the fuel system is returnless, the injectors are louder and make a ticking sound.
Nothing to worry about, just turn your stereo up or something to drown it out.
