Since the leaking oil is spread over a large surface area of the engine, leaks are not visible at first glance. When searching for a leak, it is recommended to:
- Wash the engine. Spray the engine with a suitable cleaner and after a short time of action, rinse the engine with clean water. First cover the ignition distributor and generator with plastic bags.
- Sprinkle talc on the joints and gaskets on the engine.
- Check the oil level and top up if necessary.
- Take a test drive. Since the oil liquefies on a warm engine and penetrates through leaks faster, drive at least 30 km on the highway.
- Inspect the engine with a portable lamp, locate the leaks and eliminate them.
