I have a 1996 Chevy Tahoe with a coolant lead at the intake manifold. I am in process of removing the manifold but having some difficulty removing. I believe I have removed all bolting but the manifold is stuborn, any hints? Also how common is the leak on this manifold, Vehicle has 109K miles, and have always used the orange coolant. I have replace water pump (@100K) due to sepage at the weep hole.

Thanks in advance
