Thanks for the replys. I did a piston soak for 24 houres with some local "Internal engine cleaner that removes combustion residues, soot, deposits, water and glycol." A lot of white smoke and now my exhaust was like a chimney! Run ruff for first 5 km but now all back to normal. So hope it have helped, need to drive for some weeks before i can conclude something.

Keep an eye on it. Hopefully it should improve and your oil loss gets better. Depending on how much piston soak used it might be better to change the oil as well. Not sure if the soak would have drained down into sump and what effect it has on oil? Depending on how bad the gunge build up it may need a repeat soak?

I filled it up in the moring 08:00 and at 15:00 and 22:00 and next moring 08:00 with 250ml eatch time 1L total. Around 300ml was added to the oil, rest puked all over my garage and in my face, total mess. changed the oil and oil filter. depending how is goes i can consider to try again.

Fingers crossed.Hopfully its a permanent fix.
