3. oil in the intercooler hoses is normal and as noted comes from CCV puck. FYI CCV or PCV has been around since the 1960s and every single one of those systems puts crankcase oily air mist into some place in the intake. No big deal but in the CRD it will cause the airbox to turbo hose to rot and tear just in front of the turbo; best to check this location at every oil change.
But unfortunately on this vehicle, it
will allow oil vapor to condense and collect in the bottom of the CAC (intercooler) over time.
On my very first timing belt change right after the purchase of my Jeep CRD, and before installation of a ProVent filter, I found about a 1/2 qt. of oily liquid in the bottom of the CAC when I cleaned it.
Another reason why these vehicles should have come from the factory with a ProVent type filter apparatus installed on the CCV system.
Dang bean counters!
