knock on wood btw, i dont want a boost leak.

what hoses could have a boost leak? intake hose, intercooler hoses? diverter valve hoses? what about the intake pipe?

anybody have diagrams from the bently?

 

In addition to the photos below there is a small hose that comes off the bottom of the manifold and runs to the PCV valve that can get a leak in it as well.

Here's the diagram for the 180



And for the 225

 

any connection after the turbo can have a boost leak all the way to the intake. But a vacuum leak can be just as big of a pita to find than a boost leak.
