Can You Drive on the Highway with a Leaking Rear Crankshaft Oil Seal?

[VonGabriel]

You should not drive on the highway with a leaking rear crankshaft oil seal and should promptly visit a repair shop for replacement. Brief on Minor Leaks: If the leak is minor or involves oil vapor, it will not significantly affect the engine. It is advisable to continue using the vehicle while monitoring the situation. For oil seepage or minor leaks, identify the location of the leak, which is often at joint seams. Sometimes, tightening the relevant screws yourself can resolve the issue. Brief on Long-Term Leaks: It is recommended to seek professional repair at a specialized shop. Although this type of leak may not immediately affect the engine's overall operation, it will deplete the lubrication system's oil (as the leaking fluid is indeed engine oil). Over time, this reduces the effectiveness of the lubrication system and ultimately shortens the engine's lifespan.
