I attempted to rebuild the valve on mine, and when I got it all together, is sprayed fluid!  I must have missed something on the rebuild, but I just gave up and bought a new valve.  Not long after I replaced the whole thing with the Borgeson steering setup. This is, in my mind, a much nicer setup.

I looked into the Borganson conversion a while ago, but I didn't like the concept of shortening the column.😱

I have never found the steering on our '78 to be "vague", seemingly the reason most people make the change.  When we bought our car 33 years ago, the system appeared to leaking everywhere - in fact the fluid was coming from the hoses to and from the pump.  Careful cleaning of everything made it easy to see that.  I've put a couple of sets of hoses on the car in 33 years since and did the PSCV and ram rebuild 5 or 6 years ago.   It's been dry ever since. 👍

I remember a friend told me years ago that 9 times out of 10 any fluid leaks are probably hoses, and in my case he was right!😄

Well, a full day of separating 40+ year old parts and a full day of installing the Borgeson upgrade and the steering is better. I think I may still need to do work on the rear end as there is still what I will call looseness in the feel of the car. I do have fluid dripping. So my questions are as follows:

1. I filled the car with power steering fluid, turned the steering slowly side to side and repeated that process until the system was full. Is it possible to overfill the system and have fluid come back out of the top of the pump?
2. I installed the brass inserts on the top of the steering box (I do not see leaks from the box). Does the high pressure line going in to the pump need the brass insert as well?

Thanks for all your help so far and thank you in advance for any further help.

FULL, as in by the dip stick level or by eyeball looking in the reservoir? Do you have correct dip stick? Depending on the definition of FULL, I would think if it is overfull, it will boil out under pressure or when in use. 

You should not need the brass insert at the pump.

If the reservoir is over full, it will likely spill out over the top as the system gets hot and the fluid expands.

Thank you, I believe that I overfilled and as the car warmed up it began to overflow the top of the pump reservoir. A moment after I would accelerate, I would notice smoke coming from the engine compartment. I believe the fluid was coming from the top of the pump and burning off on the exhaust manifold. I should have some time today to investigate further. 

Yes, it was overfilled. I sucked out the excess fluid using a vacuum brake bleeder. The car is much better. I installed the Borgeson steering gear box upgrade and replaced the inner and outer tie rods along with new adjustment sleeves. All moog parts. I have order the upper and power ball joints. That is my next set of questions for the forum:

1. Do the control arms need to be removed to replace the ball joints?
2. Are the ball joints riveted in? Pressed?
3. Anything else I should know before I dive in?

Judging from the looks of it I would guess these are original ball joints I will be removing.

As always thank you in advance!

1 I didn't remove mine. Not necessary.  

2. They are riveted if O.E M. New ones can be installed with bolts. Which are included in the set. Well...In this economy, you may have to provide your own.

3  You'll need a couple of jacks and stands. A pickle fork, a Great Big Hammer, and patience.

Since you are replacing the ball joints, have you considered replacing the control arm bushings also?  If they are factory original, then they will probably need it.

I agree, at least the lower control are bushings.  The upper A arm is a bitch to get out but the lower is easy.
