Hi-
This cam-running-flat prob has apparently been around for a while now. 
If you're into the aircooled cars, you've probably heard of Gene Berg 
Enterprises, they build Serious engine parts for the airsucker. Gene and 
Darryl Vittone (from Techtonics) used to nitpick these engines. Anyway, 
recently Gene's son Gary, found out that the cams were going flat no 
matter what the cam was made out of. And, to top it off, it was 
completly random- some would go flat, others wouldn't. They built a run 
in jig with an electric motor and it wasn't strong enough- they would go 
flat in the engines still. Finally, they built most of an engine, and 
they'd run it for 1 hr. at 1500rpm, then for 3 hrs. at 3000rpm.  So far, 
they havn't had them go flat after that, but they are still testing. 
The bad part of this whole thing is that you don't know if the cam is 
bad until you do the run in thing.
I know that the airsucker is a completly different beast than the 
watercooler, but I'm pretty sure that vw and the aftermarket cams are 
made of the same materials- from cheap to expensive. 
Now- I don't know a whole lot on the subject- but I'd call Gene Berg's 
shop in So.Cal- maybe they could let you in on what material has the 
least problems.
