Boost Leak - LewisG - 29-09-2014
So I managed to fix the common boost leak at the inlet and egr, It might be just me but it feels like ive lost a bit of power? The turbo sounds different but I just put that down to not having a leak anymore. What you think? Ive double checked that the pipes are back on properly ect

So you took the elbow off, changed the gasket and put it back? There shouldn't be any reason to lose power from doing that.
Should be boosting very slightly earlier and smoother now though, wouldn't even think its noticeable though.
Was it noisy/whistly before? If that's gone, could be why it feels slower. The feel of speed has a lot to do with noise...whacking a cone filter or noisy exhaust on always makes a car feel faster for that reason.

Yeah I took the elbow off, gave it the OCD treatment, put on 2 gaskets and gasket sealent, over the top I know but still. Yeah the turbo was loud and whistly, now you can just about hear it.

Should be well sealed now then!!
Do you get any black smoke on boost? Might've sealed it so well that its leaking somewhere else now.

I get plenty of smoke on boost
Where else could it be leaking from?
RE: Boost Leak - Toms306 - 29-09-2014
Oh you do? And its still standard isn't it, not mapped?
Well theres only one boost pipe, its black plastic and goes from the turbo to the inlet elbow, theres a silicone each end though, with a pair of jubilee clips. One of these is probably leaking boost, should be easy to see as it sprays oil about.
Only other option is the EGR being stuck open all the time, can blank it off easily.

Could explain my oil leak around one corner of the sump? Whats the easiest way to get to the pipe? Underneath?
And mine is standard your correct
RE: Boost Leak - Toms306 - 29-09-2014
Underneath is the only way really. Its not easy to access though tbh. You can also take the drivers side wheel off to get a closer look at the turbo end.
Could be contributing to the sump oil leak, but that's just as likely to be the sump gasket.

Is this the pipe?

RE: Boost Leak - Toms306 - 29-09-2014
Yep, that's the one.

I personally think its going to be the EGR stuck open.
RE: Boost Leak - LewisG - 30-09-2014
Had a closer look today around the turbo/pipes ect looks like the turbo is covered in oil, the pipes seems okay from what I can see, just the turbo
