96 chevy truck question

I have a 96 silverado with a 350 and a coolant leak. I am not sure, but
am thinking it is coming from the back of the water pump. I am
replacing the water pump. I took the water pump off and noticed there
is an orange seal pulled out from the intake mannifold in one spot. (Ot
is least it looks that way. This was replaced at a dealership about 5
years ago. (The head gasket was replaced so I assume the intake gasket
was too. What are the chances my leak is actually coming from here?
Also, is it common for a leak to develop at the back of the wate rpump?

How many miles?
Looking at the age, it could very well be the pump or a freeze plug on the
block in that area or simply a hose or hose clamp..

Pressure test and see, basic diagnostics.

I do not have a pressure tester and I have crawled over that thing with
a fine tooth comb.

It has 270000. The head gaskets were replaced about 4 years ago.

Fine, so you do not have the proper tools to check or repair this, now
