Hello scotty ,i have a vw golf 4 1.6 8 valves that burns 1 liter of oil in 500 km/320 miles,the car starts great all the time, it has power, the idle is ok ,it is not smoking, not eaven at the first cold start, the engine is dry, no oil spots under the car...what can it be?

it has 190.000km/120.000 miles

replace the pcv valve system, and if it still burns oil, live with it or rebuild the engine
