That's not a valve cover. It's a camshaft cover and it holds the cam in. You cannot remove it as long as the timing chain is connected. You have to remove the front cover and timing chain before the cover can be lifted.

There are a lot of possibilities. could be broken valve spring, problem with the cam, etc. It may have to be opened up to find out.
