Rebuilt power steering box "stikes again"

[7chargers]

I'm to believe the power steering boxes on my MOPARS will be the death of me before long. First my 68 Coronet one leaks like a sive, rebuilt it with new seals and to this day good to go! My 69 charger after I get it, it also leaks pull it out as many know is not a small project, rebuild it with new seals re-enstall and wamo still leaks.. but now it really leaks when the car is just sitting there parked It does leak alittle when under pressure when driving but dripps awhole lot more when sitting.  Now I have checked the return lines and hoses to ensure the connections are tight and everything seems legit, the actual power steering pump seems good, I thought maybe it was too over filled but still leaking. Any idea what may be the cause. I have a feeling maybe one of the seals didnt go in well and it will have to be removed but why leaking so much when parked? I did use a newer power steering fluid a clear style instead of the regualr thicker red stuff I used in the Coronet. Any suggestions or places I should look before I do the work of removal and rebuilt and take the car off the road for awhile?? Thanks in advance for your help guys/gals...

Just curious as when you say rebuilt it, which seals or orings did you replace or was it all of them? Could be one got damaged on the install.  Here's a link with some pics of replacing a few if it helps.  http://www.dodgecharger.com/forum/index.php/topic,67669.0.html

I used a complete new seal kit and replaced with all seals. Thank you for the link It just baffels me why it leaks so much when just sitting?
