Allison Doiron

So i decided to clean my throttle body and my intake manifold. Im sure to a lot of you this is going to sound like a stupid question, but when i removed a couple the hoses on the lower/rear of the T.B. there was a good amount of light blue fluid that came out. The lines go back to the top of the head. Im assuming this is because its a ported head? But is it normal that there was that much blue fluid/gas and oil that came out? Also the car is a 2004 accord, 2.4l 5speed manual.

Anyway to anyone willing to maybe help me out on this one, thanks.
