You are doing the right things by running synthetic and warming up before pushing it hard. Unless you mean letting it idle before driving it away. This could lead to cold-stacking, meaning the rings get gunked up and are not able to effectively seal well.
How much is it burning?

I didn't notice it really burning oil unitil I did the head job. The head has new valve guides, valves, valves seats and etc. I swap the turbo yesterday thinking it was the turbo going out. I didn't see a lot oil in the intake. I just put a used turbo on it still burns. It has some blow by when warm.
When I bought the motor 3 years ago it was in a 760. It had about 40,000 miles, it had a blown headgasket leaking exhaust gases through the cooling system. I put a use head on it did fine for 3 years no burning oil. I got rid of the 760 and put the motor in my 240 and notice it had another headgasket blown (leaking oil and coolant between the head and block). It never overheated on me so rings can't be cooked. So when I put the new head on I notice the burning.
Goes through a quart a week. About 250 miles. Its fine when cold but when its warm you can smell it.
