    Wrong forum, sir. You want this posted in Flying Brick K Bike but not sure adding brake fluid to engine oil will have any positive effect on your issue.

    Do you mean it's leaking from the valve cover gasket on the left, and the crank cover gasket on the right?

    Or do you mean between the black, finned oil sump that hangs down on the bottom, and the block above?

    If it's the first one, did you replace the rubber bushings around the screws? If not, that's your culprit.

    If it's the second one, I don't believe there's a gasket between the oil sump and the block; just sealant.

    Dear Preacherboy,

    Please read: http://www.bmwmoa.org/forum/showthread.php?46057 - I'm adding that info to your thread title. Also - a bit less punctuation will make your post easier to read, perhaps drawing more people into the discussion.

    Best,

    Don't

    Please don't add brake fluid to your motor oil. No good can come from it.
    If you're a gambler, got to the auto parts store and by every oil additive which has "miracle" on the label. They likely will not fix the problem, but by the time you've gone thru trying all of them, you'll have come to the conclusion that actually fixing the problem is the best approach.

    JamsinCA is right, there is no gasket between the oil sump cover and the section above it. Yah it would be a drag to have to drain the oil, clean it all up TOTALLY and put the sealant on and then retorque everything, and refill with oil. But, with all you have invested in time and money and patience, maybe that is the right thing to do. My K1200RS started doing that at some point after I did the clutch and all those seals. Or maybe it was after it fell over and cracked the valve cover and I had to replace that. Regardless, there was no way to stop the oil coming out. Mine was not a lot, but it began to get on the rear tire . Like you I was sort of tired of it at that point, but it just had to be done.

    My 88 K75 weeps oil out of most seams now, and the rear seal and oil pump. I can't complain, the poor thing is 25 years old with 72K miles.

    Anything you add to your oil to stop leakage is likely to do more harm than good in the long run. Nothing goes in my crankcase but pure oil.
