What Ryan said is a MUST!!! I'm new to diesels too and my biggest mistake was not knowing what to look for. I only got 3000 miles out of mine. Now I'm in the middle of pulling the engine /ubbthreads/images/graemlins/mad.gif
Here is a picture of my intake wheel
Check out the intake boot. Mine had a crack in it right at the turbo inlet (Sorry no pic cus I threw it away). It will have a little oil in it do to the crank case vent (ccv), but it should not be gritty (not dirt).
Check the airfilter box lid for cracked tabs.
If it's been well taken care of and clean inside and out then it sounds like a good deal.
