ticking most likely the lifters.....MBL8 from proma will fix that for a while....but doesnt last the full distance between oil changes if they are really bad. Some will say it is a band aid fix....but Ive used it and swear by it. there is also this to consider...when the lifter bores are worn oval...there will still be a ticking sound even with new lifters
