It’s a common issue in Hondas from those years. Replace the O rings, the faulty O ring in the inlet hose lets some air into the system and the power steering fluid will not be entering the pump. So, the pump runs dry creating the whining/grinding noise.
Watch this video - https://youtu.be/D0Y-Q4qtI6Y
I wouldn’t add the Lucas until you saw the problem return after changing the O ring first.
Good luck!

Thank you! Yes I've watched that video before and along with mechanic, my hands don't work well, changed those O-rings but going to check again on Thursday before we flush and replace the fluid just in case he didn't seat them or lubricate them correctly. I really appreciate your response and glad I'm a subscriber.
There is video scotty made on power stiring noise.
@klob
Thanks very much. I think I saw that one but will search for it again.
UPDATE: After replacing and testing O-Rings, flushing, replacing PS fluid and adding Lucas PS Stop Leak with no result I drove 165 miles to a trusted mechanic. We test drove so they could hear the whine. Discovered the alternator was barely alive so replaced. Drove for 45 min with no change. Then replaced the PS pump which appeared to have been pressure washed by the dealer to look like it was new. No change. Transmission checked and is good. Drove 165 miles back home and no change. Gonna just live with it and wait for whatever it is to fail and reveal itself. This is the first time in my 67 years that I've bought a used car that needed out of the ordinary work.
FINAL UPDATE: My seemingly endless quest to locate and fix the loud whine has a happy ending. Here is all that was tried and done along the way. Replaced o-rings in the PS pump then replaced the PS pump {black}:starryeyes: itself with a defective one then replaced that one. Replaced the alternator. Checked transmission, checked wheel bearings and replaced the water pump. As a last resort we ordered the rack and pinion plus the PS pressure line. My mechanic said that before we get into the huge expense of replacing the rack and pinion he would remove the PS pressure line to inspect it and replace, if needed, with a genuine Honda part. It turned out that the previous owner had replaced that pressure line with an aftermarket part which was too small. New Honda PS pressure line replaced in under an hour and instantly the loud whine ceased. Two months of fear and loathing and 3 different mechanics and all is finally FIXED.
