Discussion and technical advice the SW20 MR2. 3S-GTE, 3S-GE, 3S-FE etc
Anything and everything to do with maintenance, modifications and electrical is in here for the Mk2.
I am in the middle of making my own boost pipes up, for my pp intercooler. I have hit a wall what is the small pipe that goes to the hot pipe just before the bov location? Can it be blanked off or do i need to make up yet another fitting?

i'm not sure what pipe you mean but if you are talking about the one that goes to the air intake as well then yes, it can be blanked off.
the one that goes on the end of the standard bov??
hang on i'm trying to find a pic of a standard engine bay. impossible by the way.

i just sold that pipe to someone who said it had something to do with the air conditioning, in all honesty i havent got a clue...
have you checked the BGB to see what it says
right, if it's this pipe you're talking about then it can be blanked off, i'm sure you'll need a BOV for the car to run properly though, this pipe goes to the air intake, the standard bov recirculates the air into this.
if it's not this then sorry, i dunno which pipe you mean.
If you mean the small 'nipple' underneath the BOV, it's attached to the aircon idle up sensor. It should run through a hardpipe on the side of the head to a small black sensor near the engine lid lock, which has a 2nd pipe coming out of it going to the inlet manifold. Only exists on rev3+ and you only need it if you're keeping your aircon.
If you blank off the pipe that normally attaches to it, from memory your engine won't run. The sensor it attaches to would only be getting a (pressurised) feed from the inlet manifold and would see no vacuum hardpipe side. I would blank off the inlet manifold end and remove the sensor completely.
