What needs to worked on when the coolant is leaking into the oil flow on a 1998 GMC Sierra 5 point 7 liter 4x4?
You have either a blown head gasket or a cracked head. Serious engine dame will occur if this is not repaired. Do not drive the vehicle in until it is repaired. Probably head gasket, intake gasket, cracked head, cracked block, If there is no compression getting into the radiator, you may be able to put one of several stop leak products in the cooling system that may fix it. All of these types have a clear liquid with a copper colored part in the bottom of the bottle. May fix it, may not, but it's only about $8. I have had good luck on head gaskets leaking into the exaust.
most likely a lower manifold gasket -- gm and aftermarket both have change up gaskets, believe it or not but gm is cheaper \
