Any help ?

1qt every 200 miles is A LOT even if you had leaks!
Turbo? All PCV connected properly? Any oil in intake? How is coolant looking? Any milkshake? Smoke?

That much oil consumption is very unusual. Check the most common locations. Oil Filter Housing Gasket, rear of valve cover gasket, oil pan gasket, front and rear crank seals. Use a flashlight

Yeah 1 quart in 200 miles would either show up as a big leak or should show evidence of being burned. Check your CP for oil to see if it is making it through the inlet/turbo/TIC/IC/CP.

If it's a leak there should be oil on your garage floor or driveway. Burning that much should be seen as smoke in the exhaust, especially at start up.
