Hi, I had a slow coolant loss and hopefully I have found the issue. All of my lower intake bolts were loose. Off by about 8-10 ft pounds. My first question is, if I tighten them all up will the gasket seal again? The reason why I ask is I do not really want to take out the lower intake if I can avoid it. My second question is, if I have to take out the lower intake, is it possible to do this without removing the fuel rail from the lower intake and just remove the lower intake and fuel rail as one unit, or do they have to come out seperatly?
