Since the leaking oil spreads over a large area of the engine, leaks are not visible at first sight. When looking for a leak, it is recommended:
- Wash the engine. Spray the engine with a suitable cleaner and after a short exposure time, flush the engine with clean water. Preliminarily close the ignition distributor and the generator with plastic bags.
- Sprinkle talc on the joints and gaskets on the engine.
- Check oil level, add oil if necessary.
- Make a test drive. Since the oil liquefies when the engine is warm and penetrates through leaks more quickly, drive on the motorway for at least 30 km.
- Examine the engine with a carrier lamp, localize leaks and eliminate them.
