Is this the 5.2 engine? Loss of oil can result in low oil pressure during start up, which wont pump the lifters up quickly enough to put pressure against your rocker arms. One may have fallen off. Ive seen this numerous times. Usually it will have a loud ticking from the intake, depending on whether an intake, or exaust rocker was dropped.
