You remove the rocker cover and the rocker arm assembly. Use a valve spring compressor to pull the springs and you can get at the seals. I recommend going to Napa and getting the spark plug adapter to run compressed air into the cylinder to keep the valve in place while you change the seals. I just did the procedure last week on my V6 and used to have a 2.6L. The procedure is similar with the difference being how much $hit you have to remove to get to the valve cover. HTH
