The intake is above the head gasket area. These are prone to leak also.

I had heard that there are two gaskets that are prone to leak on the 3.8 GM engine, and that one or both of these gaskets are notorious for leaking coolant. These leaks can cause the engine to seize. I am familiar with the common configuration of older v8 engines, which seldom have significant coolant leaks at the intake manifold. I have never disassembled the GM 3.8 v6 and the remarks that I heard we re not explained in detail. That is why I posed the question. Presently, I have two of these engines; one is seized and the other is pouring coolant.
There is a different symptom for each and I could possibly repair the obvious engine defect and and overlook a potential defect that could have been addressed while the engine is apart.
