Re: powere steering leak
That could just be oil, there is a plastic cap with an o-ring right behind that in the cylinder head to access timing chain guide hardware. its hard to say without pulling stuff apart.. I would suggest cleaning it off first and doing something like dye in the oil or in the power steering (only one obviously) then when it comes back if you put the dye in the oil and it glows with a black light then you know its just the oring or the cap (or the valve cover gasket), and visa versa.
