ABOUT THIS SEAL

The rear main seal sits on the crankshaft flange at the transmission end of the Rio engine, keeping oil inside the crankcase while the crankshaft spins freely.

On Rio models this seal hardens with age and mileage, and once it fails oil weeps onto the clutch or torque converter, gradually dropping oil level and risking clutch slip on manual variants.

COMMON SYMPTOMS OF FAILURE

• Clutch slipping or reduced bite in manual vehicles
• Burning oil smell from the transmission area
• Oil residue found on the flywheel during a clutch or transmission job
• Oil misting visible on the flexplate or flywheel on inspection
• A burning clutch smell under load
