!993 SC 300 195k miles. Does not appear to leak while parked. After 30 to 40 mile drive, pan underneath power steering is full of oil. No oil around reservoir base. Lexus sevice says its a big item. Any resonable solution?

 

I would try to pinpoint the leak. Take some rags and clean up the area where it could be leaking. I've herd people use small amounts of talcum powder to see were fluid is leaking from. Clean it all up, dust some powder and take it for a really short drive and inspect. I'd look around the high pressure line on the rack and the pump. It could be a lot of things but unless you determine where the fluid is coming from it's all guessing.

I had a leak at the high pressure fitting on the pump, there's a copper washer there that I replaced and solved my leak. I was able to clean everything and determine that was the highest point of "wetness".
