Ah, I was right the first time; it is the VG33E.
There's been a lot of controversy, among the few of us who care, for the last decade about the first and second generation Quests and Villagers (1993 - 2002) being non-interference engines, both the 3.0 and the 3.3. It's a long running issue in the Yahoo Villager/Quest group and the consensus is that it's a non-interference engine in both vehicles.
One poster in the Yahoo group ("Gerry") actually worked on the joint venture for Ford and they demanded freewheeling engines since they had used timing belts on '81-'82 Escorts and when the water pumps seized on those cars, the engines were badly damaged (the timing belt ran the pump). Ford lost so much money on warranty claims they told Nissan to make the engine non-interference or they wouldn't use a Nissan drivetrain for the joint venture.
Not sure if this link will work for you, but it's a file showing a page from the '02 Villager Workshop Manual stating that this is a free-wheeling engine. The Quest Factory Manual is silent on the issue, as near as I can tell.
So, I believe Goodyear about the Villager, but not about the Quest. :-)
