B pretty much nailed it. Only thing I'll add is about the Vanos oil line. If the line is leaking where the crimp is it'll have to be replaced...but other than that I'd throw some new washers on it and snug it up. It uses bolts that go through the fitting on the end to supply oil...so if they're loose they'll all but certainly leak. May be able to fix it with the $0.30 washers instead of a $150 line.
