Yes my gf car is p/steer fluid. Wierd that is only 4 years old and it is doing it. It is normal to get a little fluid I think but not much! Usually would be contained within the boot. Maybe it has a little split you can't see or just the cable ties arent very tight. If under warranty get it fixed otherwise Id probably suggest leaving it unless it is really bad

dont spend over $30 for 5 litres unless a lot of track use and change every 4-5000kms. Not worth it! Unless of course you are making more than 50% above stock power levels then you might want to consider better oil...

rack end seals are worn/going hard. You can get a product from lucas (in a white bottle about $15) that stops leaks. However not sure if this is great for pumps etc. Put it in my gfs car, still leaking a bit from rack but better. The level doesnt go down much but there is wetness around the boot. The boot is split so it comes out. If the boot was in better condition it would probably just build up in there for a while.

I think you'll find that even though the ball bearing is lifting the flow and hence presure is limited because the ball bearing isn't open far enough.... Of course in this design there will be some creep still. I find it suprising that it can both control creep and boost so well, but hey if it works it works.

How effective are these in reducing wastegate creep? I guess not as good as the Jaycar but if they are 80% as good that is pretty decent.... If I'm making full boost by say 3000rpm in 2nd gear (lightly moded R33) could this reduce it to say 2600rpm?? That would be nice
