the vr was leakin power steering fluid bad (real bad, i mean like fill it up a few times a week) and we thought it might have been leaking from the RMS aswell, turns out it was just power steering that had dripped off and caught on there while we were driving. gave it a good wash down on a hoist, now it's as clean as a whistle, no leaks at all (had to replace high pressure hose). yours prolly isn't as simple as that, but if you don't know where it's comin from that's always a possibility.
