What can you use to fix a oil plug leak on a 1999 88 Oldsmobile?

To fix an oil plug leak on a 1999 Oldsmobile 88, you can start by tightening the oil drain plug to see if that resolves the issue. If the leak persists, consider replacing the drain plug washer or gasket, as these can wear out over time. For a temporary fix, you could use a high-temperature silicone sealant around the plug. However, for a permanent solution, it’s best to replace the damaged components.
