New Timing Chain Set Loose?

Cloyes of today is absolute Chinese junk. I went through the exact same issue on a 4.0 Jeep engine last year. Finally (after three sets) got a good one (??). They have only gotten worse since then. I own a repair shop and refuse to buy Cloyes products. Was talking to my guy at O'Reilly's the other day, and he told me that he had to quit selling Cloyes to shops because of extremely high failure rates ( labor claims $$). I would keep taking them back until you get a tight set. I had to switch vendors before I got the good (??) set for Jeep. It was kind of funny that everything was different, packaging, color of metal, instructions,etc, except the part number between vendors. Obviously from a different factory. I have also found out that Cloyes, along with many other companies (Standard for one), offer two different lines of the same product, quality wise. If you find a good fitting Cloyes, it would probably be OK for a stock slant six. I mainly deal with late model 3 or 4 chain set-ups.
