Hope a new thread was ok

I have been getting oil spots on the tailgate of my 86 Westy TD. It seems to be coming from the pipe that comes from the turbo. Now before I go ordering a new one (as it looks like its past it) I wanted to check that Im going to order the right thing!
So, the pipe that goes from the bottom of the enging to the turbo is the oil feed pipe right? As in this one here?
Also, I am due a new exhaust and a family member who works for Bosal has said he can get any full system for £12.50! I have a receipt in the van documentation for an engine replacement. It says 1.6TD jx. Can anyone point me to the right exhaust system for that so I can tell him what sort he needs to order?
Apologies in advance for my useless mechanical knowledge and many thanks for any help or advice!!
