I've been putting some miles on the new engine and it's been doing fine overall. I have found an issue with power steering fluid leaking from the reservoir cap vent. After a 20 mile drive, the top of the cap will have PS fluid all over it with enough to run down the sides of the reservoir.
I'm using a new GM type II pump and a new Borgeson steering box with Royal Purple Max EZ fluid. It's tight quarters on the driver's side of the engine. I've wrapped the header tubes in that area and the PS lines have DEI fire sleeve on the them in that area as well. The PS lines come out of the steering box, then snake down next to the headers and around the driver's side engine mount, then back up to the PS pump.
I installed a fitting and tube in the cap this weekend to let the fluid drain to the ground. Not a fix, but kept the fluid from covering the reservoir.
I'm guessing my PS fluid's getting too hot and expanding out the cap vent. Any ideas on a fix for this? My guess is a PS cooler is in my future.

Glad to hear you got your engine/vibration issues all worked out and that new engine is purring nicely.
Not totally sure this will help with your PS dilemma but maybe some worth a try.
I use GM fluid # 19329449 on my Delphi 600 box with no problems but I use a Saginaw pump.
Last night, I re-routed the return line up and over the fender liner with no issue. I started to re-route the pressure line, but it's not as flexible as the return and I need to have another 14" section of hose made to make it work. Hope to get that made today.
If the re-routing doesn't work, I'll move onto some of the other suggestions.

Reroute the lines and add a cooler. I'd make hard lines that come down from the steering box and hug the up right under the upper control arms. You can then go flex from there to the reservoir and pump. You can use banjo fittings at the steering box to keep the hard lines tight to the box. The hard part will be bending the thick wall steel tubing and finding someone to weld all the fittings onto the tubes.
This is how I did the tubing on my TA. My pump and reservoir are on the passenger side of the car.

I got a new section of hose made yesterday and rerouted the lines onto the fender liner last night. I'm going to put some miles on this configuration and see how it goes.
