Hi, I have an issue with my old 1989 XJ600 51J:
I replaced the clutch (steel and friction plates) this spring and added a new oil (the same product I have been using earlier). All good for a week or two, until I noticed that the oil turns white - milky. Replaced the oil and filter with a new one, but the same thing recurred. It has been a rather watery weather lately, so I suspect rainwater, but I don't have a clue how the hell the water is able to penetrate into the engine.
The crankcase is ventilated with a pod filter and since it has overpressure during riding, I would bet on something else.
Any Ideas how the water gets into the engine? (I don't have any logical explanation or reasoning for this, so any ideas where to start with would be great)
