timing chain rubbing on cover

[AJTorris]

Ok so if I rev my 4.0 and let off I get a metalic noise of rubbing. Theres wear,marks,on my timing chain cover. Brand new long block. I got this through warrenty. Thought old one had a spun bearing. But aparently not. Its my timing chain cover. what would cause the chain to rub the cover?

Lack of the button that keeps the cam away from the cover.

There's a spring loaded pin/button in the front of the cam that rides against the inside of the front cover to keep the cam pushed back in to the block.

Does the spring wear out sometimes? Can i just buy the spring and pin?
