My 06 650 XT did the same thing. AC put numerous seals in, even put entire new rear diff. The only thing i found to cure is the fix from Bipolar, to extend tube as far as you can go and put filter.I used a suggestion from someone on here and took a 1 1/2 piece of pvc 4 inches long , threaded a fittin in bottom and threaded a inline fuel filter in top.Cap off both ends with fittings, in top..Fuel filter is one way so water cant get in, but will breath. Gives a lot of oil capacity when hot.
