I recently noticed oil coming from around the right hand top engine mount on my 1.6 02 reg focus (145000 miles) . Wiped it off and it kept coming back. Turned out the mount had failed - they are oil filled. Had it replaced - i thought the part quite expensive but only 30 mins labour at my independent garage. Thought I would mention this on this forum because I cannot seem to find a similar problem after searching here.
