    Engine 98 Ticking Noise (comes And Goes)

    In my 98 GT, it makes a kind of a ticking noise, it kinda sounds like it comes from the rear of the valve cover, it gets loud then goes away and come back again, once the car has fully warmed up it stays away until its shut off and cools down a little bit. Could be a valve lash adjuster? Or what?
