GalaxyF

Hi, new to this and hoping for some advice!! Had some running faults with Galaxy 1.9 TDi (130 ASZ) which kept stalling and cutting out. Before I had a chance to take a look it cut out and failed to restart. Have started to look and found that when I remove the pipe going from turbo to intercooler the engine will fire up and run, throwing smoke out of the turbo in the process!! Also when it runs now I have a very bad oil leak which appears to be coming from somewhere around the EGR? I know these suffer badly with both EGR and turbo faults so am I likely to have to replace both turbo and EGR to fix? Or is there something I'm missing which will fix both faults? Because it wont run with turbo pipe connected does this mean the turbo is faulty? Or blocked etc? Any help/advice/suggestions greatly appreciated in advance! Thanks.
