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

no, I don't think the stock plate, the two cantons and the 90 degree adapter are all bad, and I refuse to believe I'm so stupid I cant put this together (I can see me screwing it up once or twice, but I must have had bout a dozen attempts by now)

that's why I'm thinking the leak is coming from the block

Are you aware that the gaskets go on the stock plate and the 90* adapter in a certain order? The paper one and the cork one have to be in the right place, or it will leak. I forget what order they go in but if you don't get them right.......leak.
