This is home related but not home construction. I am about to embark on something I haven't done in years. This is replace the intake manifold gasket on my 3.4 liter GM engine. The last work I did on ANY engine was way back in the 70's on a Buick. My engine experienced maybe four occurences of overheating, twice to red lined and no more. It is now sitting in the driveway waiting for the car doctor. Can anybody give me some tips that I should know about? I know after reading a bunch of stuff that GM has new bolts for the intake manifold. I know the new gasket needs to be beefed up so as not to leak again. I know dexcool is not the coolant of choice but some recommend against using the green coolant. This engine has about 146,000 miles on it. I read about the O ring on the fuel rail. Now to go finding a torque wrench with in-lb rating and crow foot metric tools.
