A lobe on my brother's billet roller got similar damage using using CC 857S when they first came out, bought the set around 2016. The plunger got stuck down and the roller wheel broke. I sent the cam back to CC and they welded it up and reground the lobe good as new.

Did they give you a new set of lifters?

They fixed the cam for free and gave me a new set of lifters. I had all receipts, pictures etc documented. 10 out of 16 lifters had stuck plungers and I followed the install instructions to the T. I figured out it was the the anti corrosion goop they assembled them with using another set I had that caused the stuck plungers.

This is pretty much exactly what Lunati tech told me when I called them regarding the noise my lifters made. I inquired about why initially they were quiet, but after about 500 miles, the clacked.

I was told they use a protectant that can gum up and cause the plungers to stick. They recommended running Sea Foam through the engine and changing the oil, but that never helped anything.

The Johnson's I ordered from KRE and put into service immediately, I don't recall being coated with anything. They were dry, at least externally.
