Just got the impreza on wednesday and as you do with a new car i was looking round the engine bay and noticed this and was wondering what it is and why would the pipe be disconnected from it and bunged? I have a 2006 WRX.




Thanks

 

looks like the recirc valve pipe, i`m guessing you are running a vent to atmos dump valve

 

ive only had the car 2 days and the dump valve looks standard, certainly doesn't make any noise. Will this effect performance?

 

have you got a pic from higher up cant really tell whats what

 

That's a secondary air pump if I'm not mistaken. It comes on on cold start up for a minute or so, to burn off catalysts in the exhaust I think.

Not sure why it would be disconnected though?

I think this is it, not my area of expertise though LOL

Would guess that the previous Owner had problems with the 2ndary air system and has pulled the fuses, either that or the air pump no longer works.

If the valves are still operating then exhaust gas can travel up that pipe into the engine bay and usually destroys the air pump.

 

oki doki guys thanks for the replies guess ill be leaving it alone, Hey midlife i saw in that link you posted that you use stan palmers ? funnily enough this car is from up that way and been serviced there.

 

PM Rob84 on here and he might be able to give you some more info on the car
