need advise please! got a wrx uk300 not had it long and already pulling my hair out! apparently got a boost leak when i put my foot down i can feel it holding back and there's a loud air/whistle noise, ive already change the y pipe under the intercooler to the turbo and the pipe that goes between throttle body but still the same! anything else i should check/replace???

 

check the intercooler itself m8, they can crack, then check all the little vac pipes, actuator pipes ect, good look

 

Check the dump valve, make sure it's bolted up tight to the intercooler and that the gasket is in good condition.

 

ive checked both of them dump valve seems fine but its 1 of the adjustable ones thinking maybe worth changing just to check.

 

is it possibly maybe the dump valve can stick open??

 

Definitely put standard non leaking dv on

 

Yeah that's what i was thinking suppose it only takes few minutes to do and will eliminate 1 problem.

 

For the life of me, I cannot understand why people remove the recirculating dump valve to replace it with a VTA.

You gain nothing, unless you count the noise

And you stand to lose a lot.........

 

Yeah i know what you mean it was already on when i bought it not my choice.
i got hold of a original 1 today but turns out it isn't that.

 

Find a local garage with a Smoke Pro. It fills your inlet & intercooler pipes etc with a harmless smoke under low pressure & finds the leak. Only takes about 10 mins & saves loads of grief.

 

Yeah iv asked a few but they haven't got 1 most garages round here just want to play mechanics doing oil changes. im just going try a few more things then if no luck a Subaru specialist it is.

 

I had same problem few days ago,,,,, check mass sensor and solenoid and also check if ur speedo works sounds daft but there is also a sensor that makes it rub rough without speedo the soilnoid should be makin a ticking noise when engine is tickin over if it's not ticking then u need get a solenoid I hope this helps pal good luck

What was your car doing? my ticks over fine and the speedo works just sounds like there an air leak under pressure.

 

Where are you Gary mate, Iv got a smoke pro.

 

Ticks over fine but when boost darted to kick in somewhere around 4/4.3k rpm it will just cut out and a huge amount of power loss just try checking every plug also please check if engine check light is on , also look under your steering wheel just about above of the clutch pedal you will see to black connectors join them together and count how many times it flashes that will tell u your problem look at jolly green monsters home page I think there is a chart that tells you how ever if not google them they are quite easy to find

 

im in Manchester mate.

 

I'm from Bolton just stick those two connectors together and engine check light will flash count how many times it flash and it'll tell you what's wrong

 

il have a look mate where will it flash?

 

Sorted it at last i think after spending time changing pipes and dump valves and gaskets and sensors, got hold of a standard wrx intercooler and pipe work and undertray to fit, put it all on today and took the stupid oversized intercooler off and all seems fine so fingers crossed its sorted. Can only think the intercooler itself was leaking.
