My lack in boost pressure?

[Rory]

rory what was the bit of blue smoke initially for a couple of minutes when it first happened though??

only happened a bit when i let off the throttle?

PS the noise was like a whistling noise from the turbo like it has always made....

Unburnt fuel going through, by the sounds of it.

Try every join in your cooler pipeing and all vacume hosing, there will be a leak somewhere.
By the sounds of it, your turbo is fine, the black stuff on the inlet, im unsure about though.
Seems to me, when you were giving it some, a vacume or joiner has split under preasure, giving you an instant loss in boost.

Keep things simple, dont run before you can walk. IE: try the simple things first stc stc.

@wallace glanza..... haha, yeah but at night you seem to hear it more distinctly lol.... **shut up dan** yeah im chatting shit again lol....

@adam, i havent got a spare blower to just wack one unfortunatly.... and dont wana fork out if by chance it isnt the turbo.....

will do rory.....

im going to rip the bumper off to get to the joiners and inspect every last one of them and see what i find..... i seemed to have puzzled a few on this one including my main man simon.... so will see what happens....

i let you all know what i find...

once again thanks a bunch for all your time guys, especially how irritating this is.... great help.

That turbo looks fine. /

Well no shaft play (as Dan said), no oil everywhere (as from the pics), no oil out of exhaust. That doesn't indicate a blown turbo at all.

I've blown a turbo myself (GT28RS) and the shaft play was rediculous after.

But i might be wrong who knows. You try and fix the easiest things first (boost leaks).

yes, but somtimes you cant acutallly see the damage first, could all look fine when it isnt, and also as he said he had already checked for boost leaks

 

[Dan3SGTE]

i will check all the joiners for the boost leak as blowing from one end to the other could be what timmy mentioned, only when it tries to come on boost the split will open up as me blowing doesnt cause enough pressure.....

 

[Jules-B]

very true, didnt think of that


well let us know how you get on!

Update

Here are a few pics of the turbo.. this is the black shit i was talking about... its like suit... Is it supposed to be on this side of the turbo?

 

[Dan3SGTE]

Also not sure how normal this is either but there are little black bits on the OUTLET side of the intercoller.. like little rubbery bits... could be soot particles as well....? But its not in the inlet side at all.....

Where is your rocker cover breather plumbed into?

The standard "catch can" that comes with the 3sgte.....

 

[GTti]

Hmm I had all the black deposits on my compressor on my old turbo but that was because the breather is connected to the intake post turbo.

Are you using a foam filter? It looks like dirt, I would say it's pretty normal.

 

[Dan3SGTE]

yeh using a HKS filter... and all the inside of the pipes are dirty too.... must be a shit "filter" then.... HKS my arse.....

 

[GTti]

Just dirt, wash it in warm water gently and spray some filter oil on it when it's dry. Foam filters aren't the best for daily driving, I have one on my GTti.

 

[Dan3SGTE]

yeah i will do.....

right ive checked every single boost pipe and i have found a few grazes in a couple of the silcon joiners BUT definitely not piercing through the other side... there are no leaks!!

 

[Rory]

Did you take them off the pipeing or just look?
You really need to take them off to be 100%.

 

[Dan3SGTE]

yuup....

i actually took each individual hose off and put under a very bright light and inspected thoroughly... pulling them back and seeing if there was any cracks/brakes.... ???

 

[GTti]

Driven the car since? I wonder if you've accidently fixed it?

 

[Dan3SGTE]

LOOK, heres the proof of what ive been doing..

 

[Dan3SGTE]

Driven the car since? I wonder if you've accidently fixed it?

nope.. the cars in bits at the moment..... only had time to massacre it, not put it back together...

i bet you i havent fixed it. i always get the weird problems :homer:

 

[GTti]

Now put it all back on securely and drive the thing.
