In general, there's nothing wrong with Comp products. Every manufacturer will have a small percentage of parts that will be defective or not up to snuff...that's just the law of tolerances and averages.

It's weird that only one lobe failed. Makes me think that the lifter in that bore wasn't spinning freely.

Again, this is the reason why I advise my customers to go with roller camshafts. If it is a cam failure and you add up the money now associated with disassembly, cleaning, replacing parts, etc., you could have went roller a lot cheaper.

Before you get too involved though, I would take a look and make sure it isn't something simple like an adjuster backing off, etc.
