2005 (2.4) power steering pump weeping from large bolt on the top of the pump.
There is a slight weep on top of the pump and it seems to be coming from the bolt circled in blue in the photo. Has anyone ever had a leak develop from this bolt? To my knowledge this bolt has never been adjusted or unfastened/fastened. I plan on replacing the associated o-ring #14 (Honda part number 91347-PLA-003 ), circled in blue in the exploded view. Hopefully this will solve the issue. (I've recently replaced the o-rings associated with the high and low pressure hoses at the top of the steering pump which are a known issue. Those are not leaking).
Referencing the highlighted bolt: it appears from the exploded view that there is a "spring" underneath the bolt. Is there any issue with removing the bolt in order to replace the O-ring that I should be made aware of?
Thanks in advance.

Yeah, I was wondering, can you test those power steering pumps? Or did you? Because I thought mine had a strange noise going on during the power steering line leak. But when it colder out during fall/winter, the sound disappeared.

Mine isn't making any noise, just weeping a tiny amount of PS fluid. If the leak were to get worse, ps fluid could enter the alternator and shorten its life.
Replaced the o-ring and that eliminated the slight leak. For future reference the torque for the bolt associated with the O-ring is 22 ft lb. The spring remained in place in the fuel pump when I removed the bolt so it did not "pop out".
Go to a site like hondapartsnow.com. Look up the Honda part number for your car under power steering pump for #14 in the picture above. Go to a Honda dealership and get that part number. You can also replace the #11 oring in the picture where the tube connects to the pump.
