Hi, After having a scan under the bonnet at my schrick manifold setup im a little puzzled as to the plumbing of it. Vac pipe goes from the flap piston to the solenoid valve, from solenoid valve to the vac bottle and from vac bottle to the engine vac line (brake i think) which makes sense to me. however up on the firewall just below the pollen filter area there is a valve that looks exactly like the schrick solenoid valve, one end of this is conected to rubber vac pipe which then links into a tiny hard plastic pipe and then T-splits left and right, the one going to the driver side goes way back and connects to the brake line.i cant see where the left side one goes it disapears under the washer bottle.Now on the other side of this valve there is a rubber vac pipe just left hanging not connected to anything,im thinking this was done when the schrick was fitted and it must be for something, i cant feel any vacum coming from this pipe at all.the wiring for this valve goes up and into the loom. does anyone know what this could be and mab why it has been left loose,im feeling my schrick isnt plumbed in properly? sorry i dont have a decent pic thanks in advance

the pipe that runs to and under the washer bottle, goes to a vacuum accumulator for the interior airflow control, (if you have air con) it controls the flap for recirculating inside air or drawing from outside, its on the innerwing behind the arch liner, im pretty sure the other side of that valve is meant to be connected to the brake servo vacuum line, hope this helps as i dont have much experience with the shrick setup!

thanks guys.i really wasnt sure what it was. and now that i think ive always had a wierd sort of light buzzing sound when i have recirc button switched on,the loose pipe may explain why i keep getting a 00533 idle air fault code every day or two.

Id rather have it connected as stock if i can. so the free end of this pipe will go to a vac feed on the brake line right? so i should just be cool putting in a tee piece on the brake hose and connecting it yeah?
