oil baffle vs. windage tray On the picture above the factory BMW part on the oil pan is the windage tray. That keeps the crank from slinging oil down into the oil pan in creating air bubbles in the oil. The next step is an oil baffle, which traps the oil around the pickup during hard acceleration or hard cornering. The little doors only let oil flow in around the pickup and then won't let it flow out, or slows the flow. |
