Hello again! After I also had the problem of the restless engine run (sometimes with misignitions?), I gave my ’95 850 10v a new set of spark plugs. Which was probably also urgently needed! They partly looked not good at all.. Engine runs round again, so everything is good. Oil consumption is still high, but so far I had the VSD in suspicion.. Blue clouds and so.. To the current thing: One of the spark plugs was very black and it was oil below a and the candle. I then wiped out what was going on and it looked like the oil from above (cylinder head gasket?) would run into the shaft. Not from the very top! It still accumulates some oil there, which I now do more or less regularly.. Now the question: cylinder head gasket? valve shaft gasket? And are there flat cost estimates on your part for such repairs? Was already via SuFu on the way, but the listed cases wanted to fit somehow not t.. Best regards, your Nico Achso, in the appendix a picture of the situation immediately after the first opening before the CC change.
