I haven't ever been the type to push something hard and hope it breaks loose in a good way.
It's not some " I can barely hear it taping " sound, nor is it a " Well that engine is going to need to come apart ! " loudness either. But if I was going to sell it, down the road, I would loose a few thousands bucks in haggling, for sure. I would also worry if it's something that is only going to get worse and it's cheaper to fix now, than let it mess other parts up. Changing a cam is not what I would want to do.
