So here is a picture to help :
The DIY included above is a bit misleading for a GR as they mention removing the intercooler to disconnect the crankcase breather from under the throttle body, that's not exactly where it is on our car.
The good news is that I think that just disconnecting the check valve from the inlet can capping it would allow an intake test to be done without removing the intercooler to cap up any hoses sitting under the throttle body.
Now my question, I did pull to try to dislodge the PCV check valve (which I think is that that white thing is called) off the inlet but it was stuck in there pretty good. I didn't have the balls to pull as hard as I could have. Has anybody been sucessful removing it ? If so, what did you remove ? The inlet side or the other side ?
In that video, they seem to remove the other side but the crimp on that cable doesn't really look like it can be re-used besides, the service manual shows the valve and the rubber line as one piece of assembly that comes off so that would suggest that it should come off from the inlet side.
