I have a '92 that I just put back together after completely rebuilding the motor myself.
My issue is the thing has a power steering pump whine that is louder than the blower over 3k rpms.
-PS rack and high pressure hose are new in last 500 miles (and supposedly new pump but not sure on that).
The details are:
-NO leaks anywhere fluid stays spot on full mark, cold or hot levels.
-TOTALLY flushed about three times with ATF Type F fluid (has an anti-foaming agent that makes it work better than Dexron types)
-Hooked electric vacuum pump up to reservoir top via special tool that pulled vacuum on resevoir to bleed system and pull any air out of the circulated fluid.(Ford prescribed but also a top method on all cars.)
-Turned rack-to-rack, but not holding > 10 seconds.
-When I finish the above steps, it's fairly quiet, and fluid is nice and clear, completely new looking ATF.
-I take it for a test drive, and pretty quickly the ATF is very cloudy, not milky but cloudy from air. I pull the ATF out of my resvoir with my Vacula and fluid is clear as new after sitting for a few hours.
-Removed serpentine belt and engine, jack shaft and blower are nice and quiet Alternator turns smooth and water pump is new
-PS pump feels smooth, but has a little end play when I move the pulley horizontally in and out. I think a little is normal if I remember right, stays centered via the pulley\belt.
-System turns great, but may be a little touchy with too much assist at highway speeds.
Points I'm considering as the cause, add yours or please expound on my ideas.
- PS PUMP IS BADDDD - this is my logical guess OR
- Air is getting pulled into the system evidenced by the cloudy look (but not milky)
******I think this is return side because no leaks and maybe the pump is pulling in air but wouldn't leak since it's low pressure and on the return side
What do you think? Any idea would be welcomed.
Thanks
