If it froze this bad. It is probably a wise idea to dissasemble and clean the rust out.

Problem may not be with the lifter. They usually will not stick up in the bore.

I lean towards a stuck valve possibly. Alot less lubrication in this area and most likely to stick. As lifter comes up the push rod meets an imovable object ( valve ). "It Bends". Seen this before in other engines big and small.

What do you think Merlin 2021.
