So Ive gone through the threads in search of my holy grail. Forgive me for beating the dead horse here. So recently bought this 08 Pilot. To replace my 95 Accord (still runs!) To recap my steps here ive changed the O rings on the inlet and out of the pump. Got em from Honda along with 6 bottles of fresh fluid. I pulled the resevoir and cleaned it well. There was no residue on the screen and not much else i was suprised based on how the fluid resembled used motor oil. Checked the hoses for wear and cracks and replaced the factory clamps at the pump and the resevoir. The first time i changed the O rings I used a Felpro set. Pump sounded worse so to the dealer i went. Secont time around after firing it up to bleed temps got to operating temp and all was calm. Bled great and No noise! Yea well my happiness was short lived. Soon as i went for a drive there it was. Stupid whine again. I'm convince air is still getting into my system. I am well versed on that air whine. Accord taught me this lesson. I am at the point where I'm about to tastefully use black RTV around the pump there. Has anyone had high pressure line failure? I have also thought to check it around the frame as they slowly can wear a hole in the line. I just cannot condemn the pump after this most recent fluid flush and bleed. Again my Accord taught me this wonderful lesson I will never forget. All $200 of it. No visible leaks. Thinking about adding a dye for a leak test next. Its cold here right now so makes it hard to work on in the snow. My driveway is on an ever so slight incline. I am baffled but determined. If anyone has some insite I am all ears here.
