remote oil filter fittings tapped right into the block UPDATE in post 58 and the whole idea got 86ed

its a 75 LA
here is most of what I went through
canton oil plate...still leaking

I tried to reseal the 90 degree adapter again today and this time I know I got it clean
I used a wirebrush on a dremel and some 220 sand paper, glued to the old adapter plate
then cleaned it all with alcohol

I think at this point I need to consider there may an issue with the sealing surface
