Sorry to scare ya, but the two symptoms you desribed both go to HG.

now... the SVX does "smoke" out the exhaust more than most cars when it is running normal and there are many places for the coolant to leak... Can you describe the bubbling you saw when you pulled the cap.

Also I at first thought the bubbling you saw was in the radiator? Reading your post again, I'm guessing you mean the coolant tank behind the battery?

Just keep an eye on your temp gauge at all times any jumps up or down, and you need to stop and check the level.
