I used ATF and read 60 with the blue Moroso spring. Switched to lacquer thinner, read 50 and saw the mating surface spray. I didn't see it with the ATF but wasn't really looking for it. I haven't tried the modified cap that Alan schooled me on yet.

I don't wanna buy a tool to remove the dowels if I can help it. I'm old and this could be my last ever build. I was thinking about the copper gasket that Summit sells for 4 bucks.

I really appreciate your advice on using thin stuff, cause I'd have never thought of it. I've been building engines since the mid 60's and never used an oil pump gasket before.
