Poor man`s dye penetrate that some old timers used was kerosene and talcum powder . Clean the part first , coat it with kerosene , then dust it with the talcum powder and let it sit for a while . Dust it off and the crack(s) show up . Not as good as the new commercial ones , but I`ve seen this method used and it does work .
