It could be because of a weak head gasket,Head bolts are not tightened properly,leakage in exhaust system, crack in head or cylinder block,worn valve seats / guides,stuck pcv valve.
First of all, make sure head bolts are properly tightened and there is no leakage in exhaust system.Also check PCV valve for proper functioning.
