First, remember that the leaking oil blows all over the place as you drive... Clean it off good, then look.

Mine leaked through the pinion shaft seal - where steering column enters the top of the rack. Good place for a puddle of water to collect & cause corrosion.

All the hose fittings, as follows...
4 tube fittings around the spool valve, that's the part extending up towards the steering column. 2 of them go to the cylinders of the rack itself, so there are 6 tube fittings in all. Each one has an O-ring inside, so don't take them off unless you have new O-rings to put in.

2 of those tubes turn into hoses somewhere along their length. I suppose they could leak at that connection, but you can't do anything but replace the entire tube/hose. One of these is the high-pressure hose from the pump, so its a more likely candidate. There's a fitting (with O-ring) near the RH engine mount, with another short length of tube going back down to the pump (another fitting with O-ring). The other is the return to the reservoir. Hose clamps are easiest to check if you take the reservoir off the fender & pull the hoses through an inch of so.

Last hose is from reservoir (hose clamp) to pump (another hose clamp).

I suppose it could also leak through the pump shaft.

If the hydraulic cylinders themselves leak in the rack, they can basically fill the rubber boots with fluid, then leak out of the vent on top of the rack on the RH side.

I guess that's more than 5 points...
