Ok, first one, I'm pretty sure this is a bleed valve, but what I'm wanting to know is coolant or fuel. The brass makes it hard to determine the color of the fluid that is seeping out of it, and my sense of smell sucks.
Heres one a little further back for a reference point.
K, the next one is a sensor that says "pressure sensor". It's in the air to air manifold about 7 inches from the turbo. Is this a boost sensor? if so, why didn't gm just go ahead and install a boos guage on the dash?
Some identification on these wouldn't necessarily be helpful, but would be appreciated to keep me from pulling what hair I have out.
