    REVVING IT AND DRIVING IT AT HIGHWAY SPEEDS...... ERRRRRRRR.....

    I suggest removing the valve cover and looking... not that hard.

    WOW that sounds nasty I'll third the lifter scenario... hopefully it isn't worse than that.

    Absolutely definately positively pull the cam (valve) cover and look at it.

    You'll need to pull the cam carrier to really tell.

    Re: top end engine knock!!!

    IIRC, lifters are about $25 each (someone correct me if I'm wrong).

    Labor, I dunno exactly, but the cam would have to come off to do the job, and the cams would need to be retimed after that. Based on that, I would say not terribly cheap. If you were to do it yourself though, all it would cost is time.

    You will end up dropping around $600-$900 to fix this problem while your in there get the timing belt replaced and do the oil pump drive seal.
