944 POWER STEERING FLUID LEAK? ?

[944 DIY Owner]

When my 84 944 is cold in the mornings, I noticed some smoke coming from the engine compartment, and discovered it is spilling power steering fluid all over the place. After replacing the pump, which had a serious leak at the O-ring, the problem was much better, but there is still a leak somewhere. After replacing the pipes, clamps and fluid resevoir, she is still leaking somewhere! The steering rack appears to be OK, checked the boots etc. I'm just about to give up, any ideas? Pls help!!!
