I have a water leak from one of the small hose under the intake manifold and i am trying to remove the fuel injection system to get to it
SOURCE: bypass radator hose leak under intake manifold.
you have an internal leak at the intake or headgaskets.
SOURCE: drilled hole in intake manifold at upper radiator outlet
Did the bolt break off flush with the top of the hole? or if you remove the cover is some bolt sticking up? if there is try and use vice grips to get ahold if the bolts if it is flush then drill the bolt out and re-tap the hole. Way cheaper and likely less work too...

There is a heater core bypass pipe that runs from the block (under the manifold) to the bacl of theengine where you will see a flat rectangular "sheet metal" thing with a pipe coming out of it. The a rubber hose connects. You need to pull the top air plenums and intake to get to it. The p[ipe flange bolts to the block with silicone rtv as a sealant.

if the hose is by the thermostat, it is the coolant bypass hose. drain some coolant from radiator when cold and replace hose, refill system then check to make sure there are no leaks.
