This is probably what the rest of the world would call the crankcase ventilation system. The crankcase ventilation system in the 4 cyl 9-5 engines do have problems, mostly because the crankcase ventilation system the engine was designed to use was not acceptable for use in the US due to some stupid rules. A simpler crankcase ventilation system was quickly designed. Unfortunately that system do have problems and have been modified several times over the years. A malfunctioning crankcase ventilation system will result in dirty oil and that can result in turbo failure. Check the crankcase ventilation system, use good synthetic oil, and replace the oil often. > The technician showed me a > slight oil leak in two specific places from the head gasket and said the > pressure builds up and always leaks from these two places. Not related. The leaking head gasket can usually be fixed by retorqueing the cylinder head bolts. -- G–ran Larsson http://www.nospam.com/saab/
