The REASON the fluid was comming out was that the REBUILT master cylinder was resurfaced and the cap was hitting on the ever-so-slightly WIDER M/C due to the taper of the sides (outward at the bottom)and removal of some height due to the resurface job in some unnamed feorign country. I hand-filed off material on the outside edge all around and now the lid and gasket fit DOWN better. I also sanded the top surface with 600 amd a wood block to glass smooth. This had better work, I think it will.
