power steering reservoir leak

There is always oil ontop of the reservoir body. Its not a hose leak because the oil is on top.. that being said, there is also oil underneath.

I noticed that the cap has no oaring, and that there is a little breather hole in the lid (to accommodate the vacuum i imagine).

How can I make it stop? I just dont like that oil has spilled allover my alternator.

power steering reserviors are self bleeding, and is normal to see sweating or wetness on the reservior body. if your anal just clean it every week.

What the JDM guys do is use a sock, somtimes also on their brake fuild resevoir caps too, that's a cheap easy way to fix your issue. Use a new black one, not a white one from your laundry basket!

Had the same problem on my 320 e46, and found that o-ring is missing, so I took the hole cap from E90 (it has rubber o ring). now its dry and nice))

A sock has been working for me very well.

Yup - just replace the o-ring - cheap permanent fix. Always had the problem of oil on the cap and haven't had a problem since replacing it. Turns out the rubber "squares" off and doesn't seal properly...
