The engine oil pan gasket can develop a leak. Leaking oil may accumulate on the exhaust system resulting in a burning smell. Replacing the gasket should correct this leak.

Ford Windstar Engine Oil Pan Gasket May Leak
Ford Windstar Problem
Engines Affected: 3.0L V6, 3.8L V6
Average Mileage: 164,285 mi (120,000 mi - 198,000 mi)
Just discovered a very small oil leak under the front end of the van. Noticed in the last week a 'burning' smell...like plastic almost not really burnt oil smelling. Yesterday notice a slight rattle under the front end while in idle. All of the symptoms point to either and oil filter/pan gasket, or exhaust manifold/gasket or both. In any event, they're minor fixes considering the age of the car and mileage. More of an inconvenience than anything else, but definitely an investment towards the life of my car.
