One of my previous Legacy's had the same symtoms <sp?>, erratic temp gauge, and oil in the radiator, and yes it was just oil floating around in the coolant, not the milk gravy looking stuff I'd seen in the oil pans of a few old Pontiac's I've had with a blown head gasket.

I ended up replacing BOTH head gaskets and had them checked and milled, but that fixed it, cost me a total of about $200.00, but did it myself.
Probably wouldn't have been a bad Ideal to have a valve job done while the heads were off, but I bought the car in that condition, and didn't know what shape the engine was in.(hated to waste money)

So my vote is Fix it!
