Go buy an Autosure mechanical warranty, wait a few weeks then take it in and get it checked over. Sounds like the wastegate or exhaust control valve stuck open a bit.

Something about this yea, now read what I said and you should get the picture NO? If you don’t pm me ok coz it’s important not to use ppl like this company really it’s not, but if you’re a dealer don’t replay bro lol

ok and that helps me how ? i tried pull and pushing the wastegate and it moved

[Guest]

sorry, made my other post make more sence

sounds like what boostin means is, when the valve is closing be it the wastegate or exhaust control valve, its not closing all the way, so there is a slight gap for gas leakage.

to check this will probably involve pulling some stuff apart, have the valve in its closed state, and see if it is actually fully closed. most standard waste gates dont have an adjustable arm, but i beleave the exhaust control valve does, well mine did, can only say your will be the same.

will let boostin confirm though aye

Yea my car has the same prob. but even lower boost lol, 5 then 7.

tell me more about these pills. in which lines should they be?

[Guest boostin]

Smurff knows what I'm getting at. ECV's flog out quite regularly and are very expensive to replace (think 4 digits...).

Egorex, yes I work for a dealer, and I've never had any issues with Autosure. I can't be bothered taking it any further with you to be honest. And 2 other things. 1, Might pay to do an intro so we know who you are and why we should listen to anything technical you have to say. And 2, Its probably not the best idea to p*ss off the moderators.

ok good somebody else has had this problem before i want to fix it properly ive just got my car going and im trying to proove to myself its worth having a subaru lol cos ive had quite a few dramas

im going to try the intercooler valve tonight and if that doesnt work it looks as though the turbo will be coming off to check the valve or can i just undo the circlip ( without losing it) to try it?

one thing i changed from a vf19 to a vf27 would that make a difference? i didnt change anything else

[pl0x]

yea i pulled hose 10 & plumb it up like this:

and i got abit more boost but not alot, got about 7-9. the car does have an exhaust leak at the slip joint in the manifold tho

Which hose do i pull out to free boost 2ndary?

[gtlegacy]

i wouldnt try that aye im not looking for anincrease like that i have a prova ecu tuned for that and it does it by itself im trying to get my car to go like the factory wanted

Have you tried an air flow meter?? Sounds silly but they affect boost in a big way.

[gtlegacy]

i replaced mine when it was going poos with another and i didnt get the cel anymore but i guess i can try the other one again

probably dfidnt help last time i had one of the coil plugs just on

[gtlegacy]

if the idle controller isnt working correctly or not in the right spot will that mess with boost?

also i think i might have the wrong factory blow off valves on as just found one and put on to stop a leak from an aftermarket bov and just to get it running so connected up like factory

what goes on the primary and secondary ? orange and blue stripes are the colours if i remember correctly

is it orange primary blue secondary?

[gtlegacy]

anyone else got anyideas? i found out the the bovs are both factory secoindary turbo 1s so maybe that is the problem

also boost has got a little bit lower only just boost to 10psi now

[Guest boostin]

Are the turbos noisy??

[gtlegacy]

no just the usual boosting noises mainly spooling noises nothing bad like rattly or growly like bearings

[gtlegacy]

has anyone experienced what i have in the same way before? and what was the problem with there cars?

[gtlegacy]

also thinking if this problem is the ecv what other symptoms would i be getting?

i also tried the gfb boost tap the other day and it didnt really do anything at all just had 6psi and 6 psi right in and 8 11 when wound out which is a bit weird i thought cos shouldnt it just boost right up

[Guest boostin]

If the ECV was faulty you would have low primary boost but normal secondary, so its not that.

Its something that would affect overall boost levels.

[gtlegacy]

wrong bov on the primary?

it kind of makes a noise like blowing accross the top of a bottle at a certain rpm and engine load like low load going through the revs just cruising up to speed

[Guest boostin]

Sounds more like a faulty BOV. I would be tempted to replace both of them and retest.

[gtlegacy]

ok i am getting a primary bov(orange stripe) on saturday morning and i allready have another 2 secondary bovs (blue stripe) will try that

what else could it be?
