Finally have everything rebuilt from scratch and back together. Runs awesome. (1000 miles on rebuild.) But like so many of our rebuilds it has a slight lifter tick which is only noticeable from about 140 to 180 degrees. At warmed up (192) idle and off idle and foot into it it sounds perfect. Should I worry about this (seek and replace the offending lifter), use the ATF method a few times, or just forget about it? (I shouda but didn't put in new lifters at rebuild since they were pretty new.) Thanks.
