some progress.

got the upper half of the manifold off. used the double nut technique to get all the studs out. is it a good idea to use bolts instead of the studs, or should i put the studs back in?
but i checked for the coolant leak, and i could find anything directly. but i think it may have been from the little fitting thats right next to the spot where the upper hose connects on the intake mani.
as for the vac lines, i checked them all and everything seems good. i couldnt find any leaks. i replaced all the vac caps on everything i blocked off too. i also cleaned the IACV and the one next to it, and redid the RTV on the EGR block off.
is there anything else i should go over since i have everything apart? is there a more efficient way of checking the vac lines besides plugging one end with my finger and blowing into the other end?
