hello car use to run 14-15 psi now only runs 5 psi all day long thinking of part ex soon but don want too ,think might be boost leak is there a way of checking your boost pipes?what else could it be? any advice would be great cheers

 

a bit of back ground info on the car would help no end.

 

its a impreza classic v3 import 1996 standard engine except 3 inch exhaust from cat back and panel filter ta

 

sounds more like actuator to me! would of though if it was leak in pipe you wouldnt even get 5psi..try a second hand actuator not hard to exchange and the springs do go weak in them

Ok cheers for reply and a link ill think i will try the actuator

 

I would do a few checks before changing the actuator.
You can check it firstly by seeing if it opens and closes easily, it should take quite a bit of moving by hand. Connect a pump to the actuator and see what pressure it starts opening at. Clean the boost control solenoid out, check the ecu for faults.

 

Let's calm down and start at the top shall we!

Here's a couple of links for you. I find the search facility very useful.

lol, before going down the new actuator route get the pipework etc checked out. if you don't know how to then get it to a specialist who can look at it for one, a quick once over wouldn't be too expenisve i would have thought.

 

Ay up mate.

Here's a thread for you.

o my good lord, even replacing the turbo and still not fixed, ge it to someonewho knows what there doing

 

My Scoob was boosting to 9 psi.... I was hoping someone on here could have given me some tips on how to pressurise my Intercooler & Pipes, but decided to remove all the piping block one end up and blow down the other..... I did this with every bloody pipe today to find the alloy pipe that runs down infront of the passenger side cambelt cover then twists around to the front mounted intercooler had chaffed through on the bodywork. I repaired the 3/16-1/4 inch hole which took my boost back up to 17psi..... worth a check mate

 

just done the jollygreenmonster test and its coming back as mass air flow sensor so will change that first thanks for the link

 

thanks for advice will give it a go

 

No problem.

Did you read the thread that i linked in post#10? Will be of use to you.

 

glad you sorted it will have a check too if other things dont work cheers.

 

yeah i have been watching that thread the last few days it all started getting a bit complicated for me with all the talk of z4 and z5 ecu s and all that stuff haha,its a good read though just waiting to see how he gets on hope he sorts it

 

Yeah, forget all the ECU and Wagon talk. The boost system is exactly the same and all the advice is relevant to your problem.

 

hello its me again been looking for air flow meter today,im after an orange label one cant beleive the prices £360???? went to mechanic today and he said purple label is exactly the same is this right?is it ok to get used one?
