I have to fill my overfill bottle every 2 days, don't think it's my HG. Not smoking, overheating or idling bad at all. Car runs perfectly fine but a bit rich. Any other suggestions..........I'm going to try replacing the rad cap first.

 

coolant leak.. small, take a look w/ a flashlight.

 

Head gasket pushing out coolant under boost?

 

I'll take another look and see what I can find
