With that configuartion though such a massive leak is almost certainly  
going to be audible and should be faily easy to see with the naked  
eye, unless its in a very odd spot.

While you are in there you should pull the turbo inlet hose also and  
have a look and feel. In case you aren't aware you are looking for  
very very slight radial play (like a few thousandths of an inch), and  
imperceptible to zero axial play.
