Why Rear Main Seals Fail
Over time, rear main seals can fail due to:
- Age and normal wear
- Lack of routine oil change services
- High mileage and heavy use
- Crankshaft misalignment or pressure issues
When the seal fails, oil leaks between the engine and transmission—often unnoticed until you spot oil leaks under your vehicle.
Symptoms of a Rear Main Seal Leak
Common warning signs include:
- Visible oil spots where you park
- Rapid oil loss
- Burning oil smells
- Slipping or contamination inside the transmission system
Because this leak is located deep in the drivetrain, proper diagnosis is crucial—and that’s where expert engine diagnostics make all the difference.
