Hi, when i wanted to park the car yesterday, in parking lot, i moved the driving wheel to maximum and instead of hitting the lock i felt like it is blocked at about half way. It was not a metallic block so I had the feeling that if I force it it will go. So I forced it, I applied more force on the driving wheel and I heard a spray-like sound and I realized that power steering oil was sprayed from the place where high power power steering hose connects to the ps reservoir. So I think that the pressure in the high pressure line was too big. What could be the problem? Is there a valve that sometimes releases the extra pressure to return line? Is the pump or the steering gear itself (part connected to the drive shaft)? Thank you.

By extending it too far the high pressure valve has failed.

Remove the pump and replace, there are no rebuild kits that I am aware of, and would most likely cost mose than a reman'ed unit.
