Replaced all that, new gasket (thanks Landers) with a thin layer of sealant, new vac caps and good to go! No problems since.

I can't believe I didn't think of it sooner. I'm getting old.

the injector bleeds are exactly what i am thinking since i dont think they are blocked off and instead, open to atmosphere.
