Hi All,
I noticed that my automatic 2015 BRZ does not have a tube connected to the manifold next to the tube that connects to the PCV valve.
What is this tube (drivers side) for? Mishimoto catch can install says that's the brake booster tube but I don't think so. Radium video says that the crankcase vent. I think this is correct.
If there's no tube because mine is an automatic, why don't I have a crankcase vent? The port is just blocked off straight from the factory. Last time I checked, I do have a crankcase.

PS. Google search was no help. I couldn't find a single photo of this area with the port blocked off like it is on my car. 1st owner so I know it came like this from the factory.
