It also doesn't take alot, one good drop is really all you need.
exactly what i would reccommend. I hope the follower is not stripped causing the stud piece that rides on the vavle to move which would cause the nut to back of also. When u do the locktight thing ull find out bc the stud and the nut will try to come out. Good luck man
