    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)

    I think we just had another thread that covered this a week or so ago. Still seems if you have pods and store the bike outside the water still seems to find a way in. The pods do not keep water out like an air box. If the bike is stored outside and the elements can get to it, I would guess rain is coming in through the PODS or crankcase breather. IMHO

    If bike sits out doors and you have pods and it rains this will pull in water . The other item if you dont run bike long in cool temps, water would evaporate if engine and oil gets to high enough temp, but if not this can cause milky looking oil.

    Run it hard for a decent time > 30 mins and see if it drives the water off.

    Get a length of hose and relocate the breather filter to somewhere under the seat so the rain can't get to it.
    Better yet, put the airbox back on.

    My bike has no airbox, i simply have the OE breather hose tucked under the swing arm bracket with no filter.
    Bike sits outside, covered however, never had milky oil.
    Before i had a cover i always stuck a grocery bag over the carburetor pods when it was parked.
    Maybe just make a little cover for case breather, n keep a grocery bag handy for the carbs. :)

    +1 On trying to keep any and all water away from those PODS and or open filter systems.

    Ya, i got caught in a sudden rainstorm one day, n the tank directed water straight into 1 n 4 cylinder pods... Ughhhh
    It stalled and nearly wouldnt start.
    I had to pinch the tank in my legs to keep the rain out of the outside carbs...
    Frapping the throttle constantly, Kepping the revs over 2500 so i could suck the "mist" thru the engine, i had to keep my legs on the tank and feet on the pegs, rolling stops so i didnt put my feet down n stall. It all the way home...
    What a pain, and i probly looked like an idiot..,
    not to mention suxking water thru your motor aint a good idea.
    One reason pods suck, investing in a set of "frogskin" bags for my pods to carry if it happens again.. Lol! ;)
