Hello, with this particular vehicle you may need to examine the PCV valve (positive crankase ventilation). Unfortunately this valve is integral to the rocker cover in this car and both must be replaced as a unit as Vauxhall/opel won't sell separately. Failure of the valve is common in the 1.6 z16xep engine. Heavier than usual oil consumption may also occur with failure of the valve. Good luck
