So I'm new to the V10 tdi scene. Loving it so far. But I pulled off the intake hoses from turbos when I did air filters. And I noticed quite a bit of oil in there. I'm a little concerned about the qauntity of oil in there and now I smell burning oil after cruising on the highway. Thoughts?

All turbo bearings are deliberately designed to 'leak' a fair amount of oil through the front compressor bearing. This excess helps to keep the bearing cool. Thus the engine oil inside the plumbing. It is not unusual to find a quart or more of oil accumulated in time in the bottom of the charge air cooler [aka intercooler]. The air moves through this oil pretty easily and it creates no problem in and of itself.
This is just one of those 'normal' things on a turbo diesel.
