Yep I learned that the hard day back in the 70's. Changed all the lifters in a 302 Mustang, and guess what? I still had the noise. Anytime I change lifters I change the cam now as a result of that lesson. Changing noisy/bad lifters w/o replacing the cam is asking for trouble.Sorry.
I wonder if they only replaced the lifters and not other worn parts. Causing the good lifters to go bad again.
Kinda strange its making noise so quick after you fixed. Wonder if they even replaced them or just through some MMO in the crank and called it a day ??
Hope all turns out well
