Still putting together my reman I got for a 87 T2 that I bought with fire damage.
Anyway since all hoses were either taken off or burnt I need help with this hose.

Where does the large hose on the BAC go to?

I'm not talking about the two coolant hoses coming off it, but the only other lagre hose coming off of it.

Thanks Ed

 

the pipe between the turbo and IC. where the BOV is. should have 2 holes. BOV + bac. hose is only a couple inches long.

 

Thanks that sounds right.

Now if I could just figure out where the knock sensor goes?

 

On the rotor housing, above the spark plugs

 

.Not my engine. Stolen jpg.

 

What exactly is that piece called? Is that an aftermarket one or the oem one. Where can you get that part from?

Yes the part where the bac goes to. I am having a hard time finding one. Sorry I didn't specify . (Would that be the charge pipe?) Sorry, need the name because looking to buy one.

 

it's called "the pipe in between the turbo and the intercooler"

most aftermarket blow off valve kits that are made for an FC will have a new pipe. I bought an apex-i bov kit (now discontinued) and it came with a new one.

the original one on my S5 was plastic, so I'd recommend getting a metal S4 pipe

 

it could also be on the intermediate housing at the base of the oil filler neck.

and isn't that pipe usually called the "charge pipe"?
