    Hello ,I'm new to this site, and need help
    I have 2 chainsaws both are Makita 6401's I noticed that on one ,the bar oil turns milky in tank after I use the saw,The other one ,the oil stays the same
    The saw pumps out oil on the bar and everything seems to work good except
    for the milky oil.
    Does this sound like a air leak,and how can I fix it?

    thank you

    Okay,That's a weird one.It sounds like you have water in that tank.Is this saw exposed to the weather?Rain or moisture somehow getting in the oil tank? As long as your saw is not smoking badly I don't think it is connected to the combustion side.

    You could start by flushing the oil tank several times with saw mix to ensure no water is present.

    If the oil is frothy, or looks like it was areated. It could be the crankcase gasket. Another indication of this is the saw smokes more than the other one when you first start it.

    milky oil?

    Thank you for quick response.
    The saw is kept inside my garage, no leaks in the garage
    I've changed the oil once already ,and ran the saw and the oil was milky again
    not foamy just milky ,I left the saw sit for a month and checked the oil
    still milky,I just rinsed out the saw with gas mix ,will try it out tomorrow
    I'll let you know what happens. thank you again
