ok give me the low down on what to expect when removing the exhaust manifold. i already have removed all the dpf junk. therefore it is just the exhaust manifold. truck has 215k miles on a 2007. ordered 6 new gaskets and all new manifold bolts to go back on. what is the torque to apply on the manifold bolts for installation. also will i have to unhook the turbo or what?
