Steam out the breather would only come on a warmed up motor, and would indicate a cracked block, head or leaking gasket. You might also have the milkshake effect inside you covers and pan. Water vapor out the breather is unlikely, it usually shows up in the tail pipe. Water vapor is white, oil vapor is light blueish.Excessive Pressure in the crank case indicates a bad compression ring somewhere. Do a compression test on all 8 cylinders, and check the condition of your plugs when you pull them.

Yes it did not start to smoke/steam untill around 180 degrees. It did not smell like burning oil, I got my PVC hooked up.
Whats the milkshake effect?
Thanks for the help Mike.

Milkshake- your oil will look like a nasty chocolate milkshake from the mixing of the oil and water. You can sometimes find this around your oil fill cap from moisture condensation, but when its in the pan, and on the dipstick, you got problems.
Take your radiator cap off(when cool) and run the motor, and watch for bubbles in the radiator coolant, if present, it indicates combustion pressure is getting into the radiator. Do a compression test, thats the first step to diagnosing any engine problem
