Cream colored oil...
Ok other than a HG what could be causing this? I pulled the hard pipes to start fabing up new ones and they had a water oil mix pooled inside. Checked the oil dip stick and it is cream colored. 
The car does not over heat but has excesively used coolant for a while, I could never find the leak... No smoke, and the car ran great...

On N/As they had the internal oil cooler element that could cause this, but I don't know if it can on the turbos due to the oil filter housing. I don't know where else the oil and coolant are close enough to mix outside of the headgasket...

it's definitely oil cooler seals. on the N/A it's got a core like a radiator. on a turbo, it's a bypass to the external oil cooler, but there's still an O-ring in the mix. that's gone. so do that.
You said it's been excessively using coolant for a while, I'd assume your bearings would be damaged now. I'd see about changing those too..

Sorry about that. I could be either the oil thermostat seals or the head gasket. In my HG R&R write-up, I list tips for figuring out if it's the HG. See this link:

The most reliable test in my experience is to trap the coolant overflow hose in a plastic bottle and go for a drive. If it overflows when you are on boost, but not when you drive gently, that's a pretty strong sign it's your HG.
If it turns out to be the oil thermostat seals, I did I write-up for that here:

I might just take you up on that.
Hopefully that will be the problem, I also have to address the turbo soon.
Ugh damn me for saying how reliable these cars are.
The car has been parked for 2 months now, oil looked fine then. I started it got to temp just to clear the cob webs out and that was all.
The oil looked fine when I parked it.
Coolant tank and exhaust was normal.
Coolant tank was very low though.

Parked for 2 months, with the weather we have been having, could be condensation in the crank case... Change the oil , run it a LITTLE, and change it again... water / coolant will eat up the rod bearings if it is run TOO much...
