new cam-valve /lifter tap. Help!

Just wanted to look for any thing obvious, Im not telling him I pulled the cover! Push rods are all straight, rolled 'em all. #1 intake rocker is loose no matter what, tap the key turn the engine over a bit, still loose. none of the other rockers are like that. Do I smell a bad break in, maybe not dry priming the engine? Maybe just a bad lifter?
