Yep, exactly what it sounds like. I'm gonna give that a try after rocking the Blazer side to side to see if maybe its just the drains. I really appreciate all the help, this place is so freaking awesome!

Edit: About how long did you run it with the cap off?

 

dont remember....10 maybe 15 min...long enough to heat up and see no more bubbles coming out...might not take as long ...it is warmer now.

good luck.
