Do you think the lifter trays were the original problem, even with the Vinci hardware?We have our smoking gun. This lifter is from the #2 cylinder and was starting to fail the exact same way that the Vinci lifter failed on the first cam swap. I believe what’s happening is I made the mistake of reusing the lifter trays from Vinci, and they do not hold the lifter well enough to keep it from rotating slightly as it moves. You can see the chipping damage which is present on the complete circumference of the lifter wheel. I have new Chevrolet Performance trays on the way, but unfortunately the cam will have to come out. Moral of the story: use OEM lifter trays.
