What kind of oil seal does a Mini Cooper use?
It is made of Polytetrafluoroethylene (PTFE). Low friction and minimum power consumption are the main advantages of MINI utilizing a PTFE oil seal. Other benefits include, no sealing problems with dry operation or insufficient lubrication, an operating range of -130°C to +200°C, and a low breakaway torque after standstill.
How to check the timing chain on a Mini Cooper?
Reinstall the timing chain tensioner. Using an 18mm socket on the crankshaft pulley bolt (red arrow), rotate the engine over to find 90 degrees BTDC. When rotating the engine, monitor the camshafts. The IN (green arrows) and EX (red arrows) on the camshafts will point up. Cylinder 1 camshaft lobes will point as shown.

Where does the oil come from in a Mini Cooper?
This means the leak is most likely the crankshaft seal, as the oil radiates from the pulley and doesn’t come from above. If you find a leak at the right rear corner of the engine, check if the engine oil is being flung from the drive belt to the backside of the engine.
How to perform a Mini Cooper Drive Cycle?
1. Start engine and idle while cold for 2 minutes and 10 seconds. 2. Accelerate to 20-30 miles per hour and maintain steady speed for 3 minutes and 15 seconds. 3. Accelerate to 40-60 miles per hour and hold steady speed for 15 minutes. 4. Decelerate and come to a complete stop. Idle engine in gear (DRIVE) for 5 minutes.
