Something Weird Going On!

Ok this one is for the really clued on, I've got a 89 r32 gtst 4door, engine mods are FMIC, full exhaust, Apexi power filter insert(yep running stock air box), & alloy rad. Now prob is, when car hits full boost, 9psi(lol), the rear window jet sprays the back window! So I was thinking maybe a vacuum hose somewhere is plumbed wrong. Not real sure any help would be appreciated. I know it's not a big prob, but is really annoying, & don't want to just disconnect it.

I'm not the really clued on but I'd look in 2 places for a start.

The windscreen wiper bottle has 2 motors. 1 for front and one for rear. See it is connected up correctly to the water lines feeding each front and back.

I'd also look at the boost solenoid on the firewall drivers side near the compliance plate to see if there is more than one hose

maybe a T piece or even set for an aftermarket boost gauge that has now been connected into the wiper system somehow.

thanks will do, it has a after market boost gauge on it, has a T piece, but didn't notice where it ran so will go and see where it goes.

the vacuum hose that was making the noise that was reconnected - maybe worth a double check to see where it is from and where it goes

this is the vacuum hose that was disconnected at one end. The end with the cable tie was off. And if you follow the hose you can see where it ends. The end that came off is connected to the stock oil/air seperator. As for the boost gauge, it's all how it's supposed to be.
