I have a terrible Power steering leak on my 93' Toyota 4Runner 3.0L V6 and i can't figure out where its coming from. It has leaked for years but only a little bit. Now its like the reservoir empties in a day or two. Do you think its an o-ring or something? I tried to see where its coming from but can't figure it out.

To look for a fluid leak, first you should have the car washed thoroughly all around the steering rack and the pump, then inspect it from the underside with a good light looking at the hoses coming from the pump to the rack, the couplings and the crimped unions of the rubber and metal tubes for leaks.
If the leak comes from a coupling, that may be a bad Oring.
For the defective hoses, you can choose from buying new ones or have them repaired in specialized shops that have the tools to make the crimped unions.
