so I got the intake manifold and all that jazz put back together....unfortuneately I broke off the top bolt of the passenger front bracket. No big deal for now, I thought. Wrong. I started her up and got out to check all the vaccuum lines and everything and what do I see but that I rolled the front valve cover gasket and its leaking oil. So I have to tear it down and re-do the gasket, but with the broken off bolt, I can't. How can I get the broken off bolt out of that bracket? and as as corollary, what bolt do I buy to replace that one?
