I was going through an old posting about changing the stem seals and I believe that I need mine changed in my 87 300E 165.000 miles. Just after about a week of smooth running it started missing so I pulled all of the plugs and the 5th one was definetely oil fouled so I figured with all of the miles its time for a valve job. But reading the posts it looks like the seals can be changed without pulling the head and is alot cheaper than a valve job, can you guys give me alittle more info on the process of changing the seals I would really apreciate it.

thanks
