ok im about to remove the bloody bleed valve on my 02 wrx but unsure as to what way the vacum pipes go back on the original boost solenoid?? would i be right in saying the one of the actuator goes on the bottom and the other on top or other way??
its got to come off as it just keeps over boosting and engine light comes on

 

anyone its a 2 port solenoid??

 

bottom on 2port solenoid is a vent and goes to the inlet pipe.. there should be a pipe that runs over the inlet manifold to the inlet pipe.
The side pipe goes to a T piece which then goes to the actuator and the compressor cover... there is then a small metal restrictor with about a 1mm hold in it in the pipe to the compressor cover..

subaru call the restrictor an orrifice if you need to buy one..

thanks mate. do i need this orrifice?? and if i dont use one until i can get hold of one will it still run ok
thanks

 

BLOODY HELL!!!!!
where does this vent pipe go as i just cant seem to find where it goes

 

it will run less boost wihtout the orrifice so is safe.

if you follow the inlet pipe from the air filter towards the turbo.. just before it goes under the inlet manifold.. on the top of it is a pipe take off about 5mm internal diameter.. as original it has a connector that drops to the thinner vac pipe and then runs over the inlet manifold and to the boost solenoid stepping back upto ID 5mm just before the boost solnoid etc.

hopefully it curtrently has a bolt in the pipe at the inlet pipe end etc
