crane goldie rockers, good or bad?

I seemed to have broken the adjustment nut and stud on # 4 exhaust, also bent both push rods in that cylinder in the process. I am using crane goldies 1.6, I think the rocker is salvageable if I can clean up the threads. My questions is that I read a thread that goes back to 2001 about faulty adjustment studs/nuts from crane, and maybe an oiling issue because of the cup at the top of the push rod not getting enough oil? Any suggestions? Is anyone still having this issue? Is anybody not using this setup because of continued problems?:banghead:
