Yep, learn something new everyday. I've done a couple RWD vehicle valve gaskets in the past and it wasn't as involved as it only took me a couple of hours. But this front wheel drive V6 has a lot of stuff on top before you can even reach the valve cover so took me about 8 hours. If I do it again, should only take me 6 hours for the same job (valve cover gasket, plugs and PCV valve) now that I've done it. I can see why the pros have a shop labor rate of 4-6 hours for the job.
