2. Since the oil spreads over a large area when there is a leak, it is quite difficult to immediately detect the leak. When searching, proceed as follows:
- Wash the engine. Cover the engine with cold cleaner and rinse with water after a while. Cover the ignition distributor and generator with plastic bags beforehand.
- Sprinkle the joints and seals on the outside of the engine with talc or lime.
- Check the oil level and top up if necessary.
- Conduct a test drive. Since oil liquefies when heated and therefore leaks more quickly, a test drive should be made over a distance of 30 km on a high-speed road.
- Then, by shining a lamp on the engine, determine the location of the leak and eliminate the problem.
