I just bought a 90 4x4 and the power steering fluid level drops right away after it is refilled. The guy I bought it from said it was a bad valve that allowed the vaccum from the engine suck the steering fluid out. Is he right?

What do I need to fix it? Buy a new valve or is there a kit to repair it?

Any ideas on cost and difficulty to fix?

 

well, the fluid has to go somewhere. Can you see an external leak anywhere?

 

is it draining into the crank case?
