The problem you all are having is what is known as fatigue failure. That is where the paper clip breaks after 10 bends instead of 100. All metal parts flex under load and this is true of cam lobes as well. It is true that when early chipping/flaking of the lobes starts it's an indication that the mudslide is about to begin. When parts are hardened for wear, there is a final step that imparts the "toughness" needed to handle the flexing. If this is done improperly or omitted, fatigue failure is almost guaranteed. Unfortunately, there is nothing lubricant-wise that will help. MicroBlue will not stop this problem either. The only way to stop the flexing is to park it or replace the cam. I hate to be the bearer of bad news.
