Do you enjoy just making things up. What do you mean "finally killed the engine". Please accept that this failure was not a cam or bearing issue. Look at the photos. They were fine.
You ignoring Frank's, Colt Cam's, & others work. Their work appears to be proving quite satisfactory.
Well if you had any real evidence of what you say about it working, it would help.

The postage size photos if blown up show wear to copper. Note the wear mark is on the no tab side. Other bearing show wear also.
This next photo is a CharlieT photo showing that same #1 upper cam bearing in a stock worn condition.
Note the wear mark is on the no tab side, which is the same spot the Franko6 wear spot is. (next to oil slot)
The reason I mention this is that I have been told that it is a bolt torque issue, but it tends to be a engine model specific issue. Some model engines wear in different positions because of cam position and bearing cocking. This stock wear spot is the same as the Franko6 wear spot and used stock factory torque.

The stock VW cams often wear to 80,000 miles and people report they are fine. Suddenly they are ruined. Before we declare Colt cams to be working we need some 20,000 mile US a year folks to roll up 120,000 miles on a Colt cam before we declare the Colt cams a winner. 300 mile a day drivers can get the miles but do not show the general population of driver wear experience. You can drive gas burners long miles at 300 miles a day.

I am not ignoring the other folks. I am looking for comporable photos and actual tests and comparisons of the flank wear that is going on. If you are going to compare cams you need wear comparisons, not just he knows trig and can talk a good talk. Show me the 120,000 mile US tests. To be told everything is fine does not work at times. I was told the bearings were fine, but when I blew up a picture I saw disaster. The rest of the pictures are not all good either. There are comments about the wear in the thread.

I can assure you I have been under close watch as I do my thing with the bearings. I went back in the oiling thread and in Red showed what not to do. I show cocked bearings and leveled bearings. I do links to support my theory when possible. Grace has kept me safe at times. I am not a really all together person. I am a jerk from Mississippi who through Grace pulled a valve cover off at just the right mileage to see wear start. If I had not pulled the valve cover off that day the cam would have been shot in a week / month / ?. The wear changed in 100 miles, if I had waited 1,000 miles the eddif thread would not exist. That is not my intelligence it is just pure Mercy at work.
I think it is an oiling thing. I do not think it is a cam design issue. VW has always pushed the cam timing, and they stay on the verge of what can be done. Because the cams look good right up till oiling goes away, I tend to say oiling is the issue.
Heck I know cam grinding can help. But:
You lose HP that requires a tune.
The tune destroys your fueling certification.
If you run to disaster you must buy a core.
Higher lift sometimes destroys the nose regardless of what you do to the ramps.
etc.
You asked I responded. Post some good pictures as things go well.
