fluid coming out of the breather/filler cap? sounds like the fluid level is too high. It should just be visible inside the filler tube where the cap screws onto... just up to the screen inside it, any higher than the bottom of the screen and when fluid expands when it gets hot the level will rise and it will come out.

when you say forks going up by themselves i assume you mean the motor is running on its own without pushing the lift button?
lift button stuck or contactor tips stuck?

worse case scenario it could be a problem in the function control board but i'm betting it's a stuck switch or contacts.

could be wrong though :o)
