Searched all over this site and all I found was for the gs3. Changed them out last week due to a CEL. Fyi Camshaft sprockets and valve cover must be removed to remove The Camshaft Bearing Caps. I think everyone should at least clean these out during timing belt service to avoid headaches in the future. You need to remove both sides as they both have filters in them.
Here are the pics I took of them as they sit on the cylinder heads. I removed the camshafts as well to replace the camshaft seals since mine were leaking.
