That wouldn't be so bad compared to something in the lower end...
If it was a dead lifter it would probably have to be a dead intake lifter, and only the primary intake valve inorder for it to not get any air into the cylinder. That could [censored] up the compression test. Does it do ok once the secondaries open? If so then maybe you are on to something. If not, then it is highly unlikely that there are two bad lifters side by side on the same cylinder.
A wet compression test indicates that the cylinder is pulling in some air though. He could have a screwed piston ring. A low-end knock or bad bearings won't cause bad compression like that.
