I'd say no. The covered plug is supposed to attach to the hose with the white valve on it and then attach to the TB. Where it is attached now almost looks like the vacuum line for the BPV/Heater bypass solenoid.ah well thats not how saaber 95 sees it he says
First off, that hose broke because of the pressure built up from the engine becuse someone blocked the outlet to the TB meaning your engine is not breatheing correctly. This would be a good time to do the PCV upgrade and hook every thing up correctly. How long have you owned this car? And what's the milage? Bottom line is; How long has your car been running this way? because that's not normal and it certainly not a mod that make sence.
So is it normal or has a vacuum line been deliberately disconnected?
