As long as people are willing to reply to this there will be a debate.
I never said that. They all can. This thread is about Comp Cams and it is the quality of Comp Cams that is the debate not the others.
How? I can only speak for myself. With out all the needed information I cant say one way or the other who, and/or what caused the problems. That information is not here.
Like all engine parts camshafts have tolerances these include bearing tolerances.
I said ID, not OD.
Let me break that down as you seem to have trouble reading it.
This is referring to the outside diameter of the camshaft, not any bearing.
Despite my typos here (then not them) this is referring to the bearings. I see no reference to a bearing OD here, but I'll humor you.
Camshaft bearings have an OD (outside diameter), and and ID. (inside diameter) The camshaft's OD need to be smaller then the bearings ID. The OD of the bearing is determined by the engine in question, and if someone changed something by machine work or other means.
If the camshaft's OD if towards one side of the tolerance range (smaller) and the camshaft bearing's ID are towards the other side (bigger) the tolerances will be looser. The ID of a camshaft bearing will increase slowly with wear. I also said it might be the cause, not that it is the cause. This also follows what I have been saying. We simply don't have the needed information to say for sure one way or the other.
While I did use the word bad, I also gave an example of what I meant.
Comp Cams like all others use the factory specifications for camshafts, and it is not their responsibility to verify that the customer's bearings or what not are still within factory specs. That falls to the installer, even if the installer is the customer.
I would be saying almost the exact same thing if this thread was about Cam Motion, just replace Comp Cams with Cam Motion.
Can you say that anyone that has had this issue could not have solved it with new cam bearings? I know I cant.
PS
Can anyone say that the problems for at least one person was not caused by damage during shipping? I have seen some really trashed boxes from FEDEX, and UPS. They were packaged fine, but due to an accident during shipping were damaged.

The whining noise was due to surface irregularities on the lobes not any type of bearing problem. There is no mystery to ponder here. The problem has been identified and the solution is known. Read this whole thread:

I can say that if I have a problem I would have no issues admitting it.
PS
Unlike most I don't call it wasted money IF I learn something from that money.

I never said it was not Comp Cams fault. Anyone can and will eventually find a problem with any company if they use enough of that company's products. This is just far easier to happen the more of whatever it is that company makes.

The volume thing doesn't hold any weight
If they had a problem and 500 out of a million cams were bad, would it not be the right thing to warranty the bad product?
As big as comp is I would think they would value their reputation more than the few hundred dollars they made on that cam.
I spoke with comp multiple times the last time my car was apart for a bad cam. They flat out told me if I send them the cam they would test it and regardless of what caused the damage they wouldn't not stand behind their product and would blame it on oil change interval, incorrect valve train setup, or install error and I would be out the cost of shipping with nothing gained

It doesn't matter how many cams are perfect to the people that got bad ones
Has anyone had a cam motion cam fail in the last 5 years? Even one?
For a company as big as they are, you'd think quality control would be paramount. And after the fact you would think they would stand by their product, warranty the bad cam, and hopefully change the minds of people like myself that have had a terrible product and terrible customer support.

I have not had to call Comp Cams, and I hope I never do, but from experiences with other company's customer support it will also depend on who you talk to, and how you deal with it as to the quality of support you get. No support should not be this way, but it is.
I'll use DirectTV as an example here. Back when I had DirecTV (with no contract) I would only need to call about once a year if I asked for the cancellation department first, and asked to cancel when they asked why I was going to leave. I would tell them. They would try and get me to stay, and the mojority of the time they would offer what I mentioned to keep me there. I would act like I was reluctantly accepting. The first time they did not I cancelled, because they only reason I was staying was because they put in the effort to keep me there. If I had not asked for the cancellation department unlike my friend they would have put in 0 effort into keeping me there. I don't know how that would work today however.
Same thing with computer parts where you need to call for an RMA, If you know what your are doing, act like it, and stand up for your self you will get better support. If you don't know, act like it, and don't stand up for yourself they will almost never do anything.

I love my DirecTV...
Anyway, my HellRaiser from Ed was a Comp. Looked perfect on install, and ran like a dream the whole time I had the car. Quiet, and plenty of power. I actually LOVED that cam shaft.
I myself would simply be reluctant to run another in the *NEAR* future until these threads go away. That's all I'm saying.

I have had two cams from Comp Cams. Neither had "the whine". However, I choose Cam Motion now. The reasons are: Better steel (8620), any duration and lift combo I can dream up, he finish polishes all his cam to guarantee no whine, he gives you a Cam Doctor printout to make sure the cam is accurately ground, and I can tell you his customer service if far far better.
Who wants to find out the hard way? So, I was lucky that I had no problems so far. I have never been thrown through the windshield of a car either, but I still wear my seat-belt.
