I pressurized the system and air was gushing from the back of the engine. Got my 18 year old daughter into the garage and taught her how to operate an air chuck "no small task there".
I was then able to find a split in the hose connecting the balance tube to the air regulator. I wrapped in in electrical tape and drove it around the neighborhood. Seems to be better. Will give another update once the silicone replacement comes in.
