Trim cylinder extends on its own

[BellevilleMXZ]

I have the drive off my 05 Rinker 270 for the winter. Trim cylinders are tied up by the bodies, and siting almost level.......I noticed over a week or so, the one has extending out all the way by itself, other one has not moved. Any idea what would cause this?

Oil flowing down from the reservoir?
It always helps if you te​ll us what we're working on?
Maybe a pic?

Its a DP drive......cant see why oil would flow when it not being operated. I'm assuming some kind of leaking valve?

were both cylinders slightly extended, and now one is more extended and the other is more retracted? that is common (your cylinders are tied together, and not running counterballance load holding valves)

I wouldnt worry too much about it unless the cylinders fail to hold up your drive.

Ok cool, that's exactly how it looks. Thanks!
