Well, I looked very closely at the inlet port of the Slave Cylinder and found nothing out of the ordinary, with the exception of a slight amount of rust at the bottom part of the hole. It was not in the threads, but in the conical indentation made by the drilling operation prior to threading during manufacture. This is no big deal considering that the sealing surfaces are between the shoulder of the inlet hose and the machined boss around the inlet port, which is sealed with a copper gasket. With that in mind, I took a closer look at the machined seat for the bleeder screw. Sure enough, there was a tiny streak of rust on the bleeder screw seat! Upon closer examination with a bore scope and a magnifier, that streak of rust is a tiny channel that is letting a small amount of fluid out and air in. Further examination using Prussian Blue revealed that the bleeder screw is not seating properly either, mostly due to this rust. I have another cylinder on order, of course with a week's wait.
I have been bitten yet again by the new part demon! Why doesn't anything work right the 1st time? Oh well......
