Hi everyone,Recently i went to my workshop to check on my power steering and found out the oil is dark grey in color. The mechanic says it is usually red color and points to the power steering pump as the faulty part. Since this is not an oil leak, he says it is not servicable and the grey color of the oil is probably due to some grinding of metal parts in the pump. Has anyone encountered this problem before? Anyone know how much is a new and a used pump? Thanks.cyclone9
