Last week I finally concluded that my head gasket is leaking. I've got it all torn down now, the heads are at the machine shop and I'm waiting on parts. Once I got into it I found the timing chain is also worn/stretched etc. I'll be replacing all chains, guides, tensioners and all gears except the VVTs. My leak was so minor that I really had no symptoms. I just smelled anti freeze a couple times after startup. Temp gauge never got up to halfway, no running problems and no steam from tailpipe. In fact the only way I was able to confirm it was by running a borescope down the #6 cylinder and pressurizing the cooling system to 25PSI. Then I could see a drop of coolant run down the cylinder wall. So now I'm spending my spare time cleaning up parts so I'll be ready to put it back together when my parts come in.
