Head Gasket or Radiator?

Head Gasket or Radiator?
So, I've got oil in my coolant. I was thinking Head Gasket myself, but after thinking about it, could it be my Radiator?

Oil in the coolant
The reason I think it may be my rad, is the fact that there is no white smoke, no power loss, no overheating, no other signs of issues. I know I have a leak on the Intake Manifold, but there is WAYYYY too much oil in the coolant to be leaking from that without power loss. At one point, I ran through a quart of oil in less than 3 weeks.
What do you guys think about it? Rad or HG?
*i hate life if its HG*

Check you oil cap for foam, and then check your oil for foam. If a head gasket has failed letting coolant into your oil then your oil will foam up quickly and should be fairly easy to diagnose. If not then I would consider changing the intake manifold gaskets.

The big reason I'm thinking Rad is the oil cooler in it. It's leaking way too much oil into the coolant to be the intake. It's close to a quart every two weeks.
All of the signs you said don't exist. No foam, at all.
