For the N62 common issues are, engine mounts, coolant crossover pipe, valve cover gaskets, and the really big ticket item of valve stem seals. There are others, but those are the "highlights."
The VSS causes the engine to smoke from the exhaust after extended periods of idling. When you go look at the truck, start it and leave it idling while you look at the rest of it. Then when you go to test drive it you'll either see a puff of whitish/bluish smoke or not.
Sometimes the smoking is caused by failed CCV diaphragms or vacuum leaks but it's more often than not, the valve stem seals.
