One man brake bleeding show...
So, after the engine-out service my PS was _howling_ and the whole reservoir was foamy.
Driving to buy ATF & hose clamps was apparently enough of a heatcycle & cycling the steering back and forth to bleed the air out & "fix" it.
Oh well, if the power steering starts screaming again I have all the stuff to bleed it and re-clamp the hose.
