What's up with Comp Cams ?
GoodLink I have no reason to doubt what is stated in that thread. Of course anyone would want to run the best oil possible, within price and availability constraints. I think the good question to ask now is does it make sense to go out of my way to buy vr1. Or should I just continue to use m1 because I have been successful with it?
Read the link I posted earlier. There are brands out there with less ZDDP and work beautifully because of their sheering factor. Look at what oil made #1. It only had 806 ppm of zinc compared to the rest. Its capability to protect against metal to metal contact is why it made #1. As I said before Valvoline VR1 10w30 conventional or synthetic is the best in my eyes. I do agree with you though on regular oil change intervals and so forth but no matter 100 miles or 3000 miles, wouldn't you want the best in there?

The Pennzoil that made #1 I use that in my wife's Yukon but not because it made #1, but because its the easiest to find at Walmart.
My camaro will get Vr1 though

"Hello Plustiano and thank you for signing up on CPG Nation!!!
Comp Cams uses various materials to make camshafts depending on what is best for that individual engine and application. We use a wide array of materials due to the fact that we cover a very wide variety of engines. Austempered cam cores are not used in LS applications nor have they ever been by our company. Our LS cams are made predominantly from 5160 or 8620 material. Either the 5160 or 8620 material is more than capable of handling any Hyd. Roller LS application. The difference in materials used has no effect on quality control what so ever and I am not sure what would lead you, or anyone else, to believe that it would. Also all of our cores are produced in the US and come from 1 of 2 sources. These are the same sources that sell cam cores to most every cam manufacturer out there, including the OE manufacturers. I can assure you that no “cheap” or overseas core is ever used in a Comp Cams product. When grinding a camshaft the core specifications must be as close as possible to the finished cam grind specs in order to maintain the deepest possible heat treat. That is why Comp has the largest selection of cam cores in the industry.
Comp maintains some of the highest quality control standards of any camshaft manufacturer in the world. Our cam grinds will be closer to the specs on your card versus any other grinder. We see less than 1% defect rates in our LS cams, which is lower than any other manufacturer that I am aware of. Also there has been no consistent heat treat issue of any type that I am aware of. This is not to say there has never been individual issues, but nothing that has been a continual issue. While it is certainly true that we are not perfect and we do encounter the occasional issue with one of our parts, we do try very hard to ensure that problems are very minimal and we have kept it at a level of less than 1% regarding LS camshafts.
Tolerances for our cams are:
Lobe Separation: +/- 1 degree
Advance: +/- 2 degrees if specified
Duration @.050: +2.5/-1.0 degrees
Lobe Lift: +.003/-.004
We do care about our customers and their projects because we rely on them for our livelihood. We strive to make the best performing and the longest lasting product possible. No company is perfect, but we do try. Also, if a customer has a problem with a product we do everything we can to help fix it.
I would also like to direct you toward a press release put out by Driven Engine Oil. It highlights the importance of proper engine oil especially in LS engines.

That claim is 100% false. Their quality control is absolutely positively no where in the same remote galaxy as those figures.
My statement is based off of putting a degree wheel on 100+ Comp camshafts over the years. I could also rattle off 2-3 other WELL known engine builders in this country that would also solidify my information but I will not unless they want to offer it themselves. Not everyone is as politically incorrect as I am.
If all aftermarket cams were wearing out at the same rate, then I could see this being predominantly an oiling issue. But since there are certain brands of cams that are holding up very well to today's oils, it makes you sit up and take notice. That was the whole purpose of this thread. It was not "why are all aftermarket cams wearing out so fast these days?" If that was the thread title, then you could turn this into an oil thread. But premature wear and improper intake centerline grinding are not oil related. Not if other brands are unaffected.

damn, this thread popped my eyes out.
i really don't think it's oil related though, i have to say this isn't the first time that i hear that comp cam's aren't that much as people are making them shine.

I think this thread is going to worries a lot of people unnecessarily. I agree that comps QC leaves alot to be desired but to have a thread that after a few pages basically has a conclusion that your comp cam is going to die soon is taking it to far. I understand Damien and a few others here are full time pro's and have lots of real world hands on experience and i very much respect their opinions/information and input. I SURE WISH A FEW MORE OF THE VENDORS/SPONSORS ON THIS WEBSITE WOULD CARE TO COMMENT ON THIS THREAD. I think we all know which sponsors need to chime in.
now my H/C/I is on hold till i figure out this cam situation. vendors/SPONSORS please chime in! I know of one sponsor who probably sells more Comp Cams than all other LSX vendors combined. I will bet money they don't say anything other than "our cams are great!"
Btw, my cam is ground on a Cam Motion core.

If it means anything to anyone we pulled 4 completely stock cams out of LS cars last year alone due to lobes being trashed. All of them come in with a miss that will not clear up and sometimes they have a tap that comes and goes every 30 seconds or so. 2 of those cars where never raced. Food for thought.

Crazy. Well I hope mine stays together for a wile. 12k on it so far hope I got lucky. Really don't wanna swap out cams and tune again. If tune was not so much I would pull it just for peice of mind. Then again pulling the cam out just for anoyher one ground to same specs from different supply seems silly to me. When they go what do they normally take with them?

Anyone reading this thread should look into it if their Comp setups are getting louder for no reason. If you notice louder ticks than before or more overall racket coming from the engine, at the very least pull the intake manifold & valley pan to have a peak. You can see a few of the cam lobes through the valley.
Good luck gentleman. Use a zinc additive religiously, be aware of additional valvetrain noise.
Jake, you are most likely thinking of the same sponsor i was, i will not be using that one now. Who uses Cam Motion? Maybe i'll look into FTI, i believe Ed uses Lunati.
Futral, Spartan Performance and Engine Power Systems / EPS use Cam Motion cores. I am sure there are some I have not mentioned, though they do not come to mind at the moment.
