    Tried marvel mystery and ATF that was recommended to me, and there has been no difference

    Something is loose in there. Usually lifter tick goes away on higher revs since there is more oil flow going to them, but it cold very well be lifter noise. Pull the valve cover and check the rocker arm nuts.

    If you had an inspection borescope of some kind I'd say snake it in the oil drain hole next time you change the oil and look at the #6 piston's skirt and see if it's missing any of it.

    Pulled valve cover and checked rocker arms. All tight! I had someone sit in the drivers seat and rev it up while I was underneath and the noise is very loud bottom end as well as on top? I guess I'll have to pull the oil pan next and check for pieces of piston
