Default Waterpump leak

Would a bad water pump/bad gasket cause coolant to leak into the intake manifold? I first noticed smoke coming out around the exhaust manifold gasket( because it's hot and burning off basically). Not actually sure where the leak is coming from looks like the bottom of the block around the water pump area. Still removing parts of the engine so I can get a better look

Could be a loose/leaky intake gasket as coolant flows through it.
If leaking, could be going into combustion chamber and coming out as you see on exhaust manifold.
Pull spark plugs and check them. A really clean electrodes and insulator means leaky gasket allowing coolant coming into chamber.

I did the combustion test, blue liquid stayed blue so I'm not getting any combustion gases in the coolant. Two of the spark plugs are really hard to get to because I dont have the proper extension and angle pieces. Can I rule that out off that alone? also I did remove everything around the water pump and the leak is definitely coming from water pump.

There is, by design, a weep hole, on bottom of pump shaft portion of housing.
Its purpose is to show when shaft/impeller seal leaks.
Pulley does cover up the hole, so pulley may have to be removed.
Look at porcelain on spark plugs as they may look brand new if coolant was leaking into chamber.
