Lubrication System

1999 Ford Windstar Base, Van Cargo, 3.8 4SECTION Lubrication System
WARNING: This page is about a different car, the 2010 Mercury Milan and 2010 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.

The engine lubrication system operates as follows:

  • Oil is drawn into the oil pump through the oil pump screen cover and tube in the sump of the oil pan.
  • Oil is pumped through the oil filter on the left front side of the cylinder block.
  • Oil enters the main galley where it is distributed to the crankshaft main journals and to the cylinder head.
  • From the main journals, the oil is routed through cross-drilled passages in the crankshaft to lubricate the connecting rod bearings. Controlled leakage through the crankshaft main bearings and connecting rod bearings is slung radially outward to cool and lubricate the cylinder walls, as well as the entire connecting rod, piston and piston ring assembly.
