Fixing air control valve on power steering pump
Losing power steering fluid and exhaust blowing white smoke? your air control valve is most likely leaking. i read people just plugged it up with a bolt and washer, but some would like to keep the valve.
here's how i fixed it.
Needs
2 O-rings
air compressor nozzle
valve
with your air nozzle shoot some air in the valve and a fitting will come out. USE YOUR HAND AT THE END OF THE VALVE TO BLOCK THE FITTING FROM FLYING AWAY.
here's what the fitting inside the valve looks like. replace the 2 black O-rings, you don't have to replace the white teflon bands. reinsert the fitting back into the valve and it should be good.
O-rings are very small. might be tricky to find. if you do find some. it shouldn't cost much.
i have collected a bunch of random o-rings over time and had some that fit.

when this air control valve seals are compromised, they allow the PS to leak into the intake tract thus burning off during combustion, not leaking out onto the alternator.

The (inner) diameter(s?) and width(s?) of the channels where each O-ring nestles is helpful
There are numerous grades of Viton, so will share sourcing information.
Thanks in advance for input.
