3rd member gasket leak
Cleaned both the housing face and the 3rd member mounting surface with a dry cloth then a microfiber with brake fluid on it. There were some little pieces of gasket in the housing so I fished that out.
The housing mounting face has some little inverted dimples on it and it looks like there is a little crease on the inside where 2 pieces of metal were welded together. I'm for sure going to use rtv on both sides of the gasket and pray that I dont leak again.
