Comp Cam/lifter failure

For a cam to fail in 10 minutes there is obviously something drastically wrong like with surface finishes or serious mechanical alignment problems like worn lifter bores or something causing partial oil film thickness (assuming you followed the manufacturers start-up and break in procedure). I have a hard time believing it could be a lubricant issue if you are running the correct viscosity. Lack of anti wear additives would be a longer term issue. Just my $0.02 :)
