So, my power steering is leaking fluid. I initially thought it was a split hose as quite an area was drenched in oil. However I could not find a leak whilst the engine was running and the steering being operated. Now I have realised that it doesn't lose any oil at all whilst running, just while standing. My experience of low pressure oil leaks in my past has been that they are normally just a very small amount. However in this case I am losing around 1/4 litre over night! I haven't had a chance to clean up the bay to see where the leak first develops yet, but anyone come across this before? I don't see how it could be coming from the rack as it wouldn't hold that much whilst standing, and the valve would be closed????
