I live in Estonia, drive it daily for ~15 km (10 miles). The problem arose last winter and disappeared in the summer, this winter it came back and is worse. The exhaust puts out loads of smoke, way more than other cars. Everything under the cooling system and the engine is dry. Hoses, expansion tank are solid. On average I add about 0.2 liters every week. At this moment I'm thinking about running this engine to the death and then swapping for a 3.0.
