Oil in the cooler – Oil consumption – end in the moose area?

Hello, just now I was still happy about my manageable clutch taker cylinder repair (was only the blast ring) and now that: that the good 1996er 850 2.5 144hp at 310,000 km mileage could consume oil, I had already thought. A Volvo screwdriver even meant 1 liter on 1,000 km they still ok. But now I have real oil in the cooling water balance cylinder! The cooler seal supplement can’t be that someone had advised me 2 months ago when I just I noticed a week ago, that the good one at the full-gas-acceleration on approx. 3,200 tours put in a hiccups-moderate pad. Then I had noticed that the engine-ventilation line was floating around freely and spitting oil. The bayonet clasp on the air supply had gone up. I fixed it again. Now I suddenly sense terrible and think the engine is as good as it is (cylinder head seal etc.). A My luck couldn’t have been that short, couldn’t it? What do the old moose-hate mean: is there still hope, or do I have to go on moose-hate now? The current moose has an AHK anyway. And he still does. Greetings, Jürgen
