Engine Smoke for a couple of seconds after short ideling time

I called my local dealer today and discussed this issue with him. He claims its the exhaust valve guide seals and it's super costly to repair as it requires engine removal and teardown. He didn't seem to think the CCV Valve theory was correct, but I may go that route since ~$30 for each side is much cheaper than an engine teardown. How difficult is it to replace the CCV valves on the 4.4 N62 motor?

Its a quick fix to replace the valves. I gave detailed instructions in another post. Search on here or take a look at all of my posts for the instructions. I still had some smoke after the replacement but after an oil change and about 2k miles the smoke has disappeared for the most part.
