Even though my car gets to spend the night in its cosy little garage, on cold mornings it likes to eject loads of power steering fluid out of the pinhole in the filler cap of the fluid reservoir. Coats the exhaust manifold, smokes and smells, and drips down and out leaving a big bright shiny puddle on the street. The stuff ain't cheap over here in Germany either! What can I do to prevent this happening? Also, the power steering is starting to feel heavy. Even after I top the fluid back up. Chaps, what do I do!?
