For less than the cost of one generic o-ring, you can silence your noisy power steering pump on most Honda / Acura power steering pumps. ****PLEASE SUBSCRIBE FOR MORE VIDEOS**** / @jefflyle
Let me know if it works for you. And if it is still a little noisy try a bigger o-ring or the oem style o-ring. I ended up switching to an oem o-ring and haven’t had a problem since.
Yes it was leaking due to the air getting in the system causing the fluid to foam up and expand. The fluid would leak out of the cap. I didn't have any leaking occur at the seals though.
