I was under the hood today revving the motor, looking for a rattle when I noticed that revving the motor produced a cloud of champagne bubbles in the coolant overflow. The engine was quite warm after driving for 120 minutes.

Immediately I suspected a head gasket and nursed the car home. The highest the temp needle ever got was half way.

So to confirm my suspicions I ran the test described here (with the car cold this evening):

"the definitive head gasket test - air bubbles in the coolant. (Whilst engine is cool) - Remove small hose to coolant tank - add enough tube to immerse through coolant tank cap. Start the car. Air bubbles? Yes ? Head gasket / warped head.
No air bubbles? You have a leak. "

No bubbles at all. Its going to a shop for a HC in coolant test which im starting to think it may pass as well.

What the hell is going on here?

Thanks!

it had a micro crack in the head that no one could see w/out magnafluxing it.

wouldn't leak when cold but when it expanded from head it would leak. fun

not sure that helps anything...
