yar i have heard about PCV (Positive crankcase ventilation) VALVE which is responsible for oil consumption and provide a vent to the high pressure in the crankcase so the oil instead of burn out it recycled to the sump, it is very cheap and should be changed at every engine oil change, but when i ask here in ISLAMABAD about the PCV valve in all the shops of the market, they even dont know the PCV valve, may be there is some local name for the PCV valve, so if anyone know the local name please provide information to me. this valve is connected through a hose pipe.
Thank You ALL
