On the 2007-2016 MINI Cooper, the valve cover gasket on N12/N16/N18 engines hardens and leaks oil onto the exhaust manifold, creating a burning oil smell. VANOS solenoid seals also leak, causing oil to pool around the solenoids and potentially cause misfires.

This issue also affects: Hyundai Santa Fe, Hyundai Tucson, Audi A4

Common Symptoms

Burning oil smell
Oil on exhaust manifold
Visible oil leak from valve cover
Check engine light
Rough idle

How to Fix

Replace valve cover gasket (the cover and gasket are one unit on these engines) and VANOS solenoid O-rings. Clean oil residue from exhaust manifold.
