Oil On Your Clutch Plate – What Happens When There Is Oil On Your Clutch Plate?

Oil on your car’s clutch can really ruin your day, especially when you consider that it may cause permanent damage. Unfortunately, oil, coolant or even rainwater can get into your clutch and ruin it beyond a simple drying out or burning off.


Oil on the clutch plate almost always comes from a rear main seal leak, but it could also come from a loose or leaking oil gallery plug or oil pan. While oil from other places may leak into the transmission bellhousing from other sources, odds are good that it won’t be enough to penetrate the clutch disc.


Clutch slippage is the first and most obvious symptom, but your nose will tell the true tale. Burning clutch material has a particular smell, something like sulphur or rotting eggs. If you smell oil burning instead of clutch material, then the clutch disc has been contaminated.

Consequences and Solution

Oil doesn’t just sit on the friction material surface; it soaks in and embeds into the material. Once that oil gets in there’s no way to get it out short of soaking the clutch in boiling solvent or caustic lye, which would destroy the clutch. No matter what, you’re looking at a clutch removal and replacement.”
