Don't know if this is like my other diesels, but I believe that the timing mark on the crankshaft will be past top dead center when the cam mark is aligned. This is, of course, if there is any stretch. Yes, you can turn it over with a ratchet and socket at the crankshaft.
Bring it over this weekend, and let's give it a try. I'll bet with the tool I have we can also get the belt tensioner loosened so that we can change the belt.
By the way, is this REALLY Ashley's car?<g>
