I took the intake off of my 496 tonight and as I was inspecting the lifter valley I found a few cam lobes with these weird little silver specs on them. No texture to them at all and they don't wipe off. Not on every lobe but a few. The one in the photo is the worst. Any ideas on what's going on here? Cam has no more than 500 miles on it, was installed by me and broken in per the instructions. I also use oil with zinc and phosphate additives. I really don't wanna break down the valves to pull the lifters out because im a lazy piece of sh*t. Am I losing lobes or what???
