Chocolate milk in oil

Hi everyone! Here's the problem.... All the antifreeze is going in the oil. I'm thinking head gasket. BUT, What about the intake gasket? The Buick has the 3.1 in it. Is there a way to diagnosis the head gasket from the intake gasket?

What year Regal?
On some models the intake gasket let loose and coolant goes into the engine. There is usually an updated gasket set available from the dealer for about 35.00.

Its a Skylark but I believe the 3.1 is in both the Regal and Skylark

There were service bulletins out about this problem. If you caught it early enough you can flush the engine with kerosene after the repair and be allright.
