Re: Name that engine noise...Please help!

Pull the valve cover off and check for a broken valve spring. If the spring is only broken in one spot and hasn't destroyed itself it may still capable of handling the valve motion at low engine speeds but when you rev it up it will not be able to control the valve causing significant noise due to valve float or the rocker slaping the valve due to excessive lash at speed.
