I can't see the pictures , flat tappet or roller ? Did the clip come completely out or only part way and the cup was cocked ?
I had a clip come part way out, cocked the cup and it stopped the lifter from rotating, ground the lobe off the cam.
Flat tappet. No...luckily for me the plunger was not cocked as it came out easy once I pulled the lifters...I have 1 more lifter to check but the previous 2 there were no issues.
