Did a boost leak test, sounds like a leak from exhuast manny or o2 housing?

The whole intake tract pressurizes and then I start to hear leakage around the exhaust manny somewhere, why would I hear that? Wouldnt the air just go right through the turbo and out the exhaust?

I also hear my coolant bubble or something when I do it, what does that mean? Im confused as to how my intake tract can affect the cooling system at all.

The bubbleing you are hearing is actually oil in the oil pan. perfectly normal.
