Power steering leaking
The power steering hose connection should be sealed by the flare on the tubing and the machined seat in the control valve when the fitting is tightened. I always heard never use Teflon tape or anything else on the threads of a flared fitting. The end cap leak should be prevented by the o-rings on the spool valve sealing to the cylinder bore. More than likely you have a newly rebuilt control valve. You probably should contact the rebuilder if this is the case. The end cap leak plagues a lot of people. Some of the T-Bird dealers supply a new spool valve slightly larger than the original to compensate for cylinder bore wear.
