Airbox look clean as in is the breather blowing oil into the airbox? Looks like water and if there is a lot int here it will take a long time to get out. You need to make sure you don't have a water pump seal leak or other issue. Then put cheap oil in it and ride it semi EZ to temperature and let it run at temp for a while. Getting water out is not EZ and the temps help. A few drops of water will make oil look real bad. I have heard of cleaning the motor out with diesel or other things but dont know about this and does not sound like a good idea to me.
looks most like water to me as well. hence why i brought it up. you never answered is the drained oil cleared up after sitting? if it does, most likely foaming. if not, im sticking with a contaminate in the oil.
It does look like oil mixed with coolant: However, Durruti has said that it started to look like that when he used the liquid gasket, so I think that maybe he was right when he said: @Durruti: how much time elapsed from the moment in which you applied the gasket until you filled the engine with the oil? What's the colour of the gasket? If it's liquid gasket, it should dry up if you don't refill the engine and don't reinstall the right cover for a day. Then, a new oil shouldn't become coloured like that any more. If it does, it's unlikely that the reason is gasket in the oil. I ran the engine with (dry) liquid gasket parts in it and I simply found them in the left twin oil filter, without noticing any damage.
Thanx for the new replies! I can't find a reason for a coolant leak, the only thing i did is remove the right cover, clean it and put it back again. Is there anything that i could have done so wrong there and cause a coolant leak? The coolant level seems stable too, and the water pump is on the left side, i have never touched it. The drained oil yesterday was cleared after a few minutes and it felt very slippery in my hand (as it supposed to) so i guess that's good news. Also, today the glass is not becoming so white when i turn it on, that's good news too (the foaming is caused by the trapped air?) I will remove these cheap oils tomorrow, and put in some good stuff again. I'll upload pics from the drained, which i believe will be normally blackish. Theo, i used a liquid gasket at the beginning, which was white. I left it to dry for about an hour before i put in oil, which i thought was enough. I have installed a proper gasket now (20€!), oils changed 3 times since then, so there's no more liquid gasket mix scenario ..(I hope). ;p
I want to know how you so thoroughly destroyed the gasket? My right side cover has been off 4 or 5 times, and I'm still using the original gasket without a hint of a leak, are the 610 gaskets that much different? The 630 has the steel core cover gaskets.
I guess mine hasn't been off for a long time, one part of it stuck when i pulled off the cover and damaged. It wasn't completely destroyed, I was just afraid to use it again.
Cheapest way to flush a suspect motoroil/water mix, 1. Drain 2. Replace plugs 3. Remove rocker cover and oil filter. 4. Fill motor w/diesel fuel from top down. Water likes to hide around valve spring pockets. 5. Repeat process 6. Drain put any cheap automotive oil that has detergent package in it. Put filter back in 7. Ride 5-6 miles 8. Drain it, capture some oil in a glass jar give it an hour to see if foaming goes away if it had some water still in it there will be a seperation. 9. Replace filter and use your normal oil go ride it for couple hours if ok the heat will burn off any traces of water that was hidden. 10. Save the 2nd drain of diesel for future parts cleaning, and drain oil for future chain lube. Later George
