My mom has a 99 explorer 4.0l that has a hole in the driver side valve cover. What happened, was the guide for that chain broke and flew into it, breaking a hole in it. Now, I want to replace the guide (I am assuming it's the guide, it's on a moveable arm that the tensioner pushes in to, with a plastic piece that WAS connected to it before it broke).

Do I have to remove the timing cover to do this, or can that piece be removed without removing the cover?

I can provide pictures if needed, but to best explain the part:

the tensioner mounts into the side of the cylinder head, and pushes against this thin piece of metal with the plastic attached to it. The plastic pushes the timing chain inward and makes it tight.

I'd pull the cover and make sure there aren't any other parts needing work. That way you'll be sure.
