I doubt it won't require major engine work, although I'm not an expert it happened to my own Windstar and it had a cylinder head gasket blown letting water into the chamber through valves so I could see white smoke (vapour) from the exhaust. It was discovered on time as continuing the use of your van under this condition can damage the whole engine.
Hope this advise help you.
