Unstoppable Coolant Leak

12ft/lbs? I been doing AL intakes wrong forever @ 35 ft.lbs. But I never had one leak either.....interesting. Weiand states 25 ft/lbs and also calls out .050-.060 soft composition gaskets for aluminum intakes. I dont think I ever loosened something and had it stop leaking...'cept maybe a Holley 1920 bowl....
