This summer I bought my first-ever BMW, an R1100RT 1999 model that's had a pretty soft life. I figure the best first step is to change the dirty oil. Yes I heard the warnings - do not overfill! Sure enough, I overfilled, showing out-of-sight in the glass. Not too bad I thought since I drained out only about a pint or so to get it lower in the glass. Ever since, it has been blowing air+oil past the valve cover gaskets. Did that extra oil mess with the PCV system? I've opened the drain plug at the bottom of the throttle body box and a little oil did come out. Changed out the gaskets and the bolt grommets, no improvement. Anyone got any suggestions?
