Some of you may know I bought the red UK TT in my sig with a seized turbo. After carrying out the latex glove test on the pipe it turned out to be the drivers side turbo which was not working, not the passenger side like the previous owner had been told. Yesterday afternoon I started stripping down my engine ready to replace the drivers side turbo, but upon removal of the large hose from the turbo to intercooler, I found this big split going half way round the hose (turbo end of the hose):

 

 

 

 

 

 

 

 

 

 

 

The car ran fine before (no spluttering etc) just that the boost needle didnt go past 0 and there was no boost.

 

Could this split be enough to stop any boost? I guess it could be but just need confirmation. I have a spare hose, should I fit this and build it back up or continue with plan 'A' ?

 

Any advice would be appreciated! :bow:

no you'd still get some posative boost, tape it up and try it but doubt you have any luck.

that pipe looks like it is from the air filter/maf to the tub. is it the hard pipe?

 

if so it would not cause a boost leak but would run lean on boost

Your not gunna get any positive boost with a pipe looking like that.

Looks like the plastic supply pipe to the tub.It would not cause a boost leak but let unfiltered air into the turbo which would not do it any good.Probaly is goosed mate.

Thanks for the responses guys.. bit of a mixture of views! Do you think I should carry on taking the engine out? Is there any way you can physically get to see if the turbo is seized without taking it completely off?

Have to agree with jimmytt. If this is the pipe from the turbo to the intercooler, all your "compressed" air is going back to atmosphere. Any pressure you might make with the other turbo will be vented back through the balance pipe.

I think jimmer knows which pipe it is more than me, hes taken off a few in his time........

Would agree - if this is the compressor side to the IC then its your problem. All boost escapes here from both turbos. If you are already at the turbo end of the hose can you not get a feel for the turbine blades to see if they are freely turning? If so you might be on an easy repair. When they seize they tend to go solid. If its still spinning its probably OK.

Thanks for the input, I'm gonna try and get to the blades later, although this side there is a long metal pipe connected to the turbo so may try the exhaust side. Would be good if this was the problem all along, well besides getting it just about ready to lift the engine out :D Not gonna hope too high though, but we'll see!

If the pipe is plastic which it looks like then its a supply to the turbo.Any pressure pipes are metal joined by rubber.

Its a rubber pipe. Its the one with the flexi section in it on the drivers side.

Inlet hose and not boost related then.Time to pull your engine bud me thinks.

in which case it is the supply to the turbo and caries no boost.

balls. oh well thanks for the advice guys, is only about half hour from bring out anyway :dance:

How's it going?

Decided to continue with the turbo replacement, but I've been busy pulling the silver one to bits to get it out the way, will be back on with this one probably next weekend, its all go at the minute!
