2. Since oil spreads over a large area in case of leaks, it is quite difficult to immediately detect the place of leakage. When searching, proceed as follows:
- Carry out an engine wash. Cover the engine with cold cleaner and rinse with water after a while. Cover the ignition distributor and alternator with plastic bags beforehand.
- Sprinkle the connections and seals on the outside of the engine with talc or lime.
- Check oil level, top up if necessary.
- Do a test drive. Since the oil thins when heated and therefore seeps through leaks more quickly, a test drive should be made for a distance of 30 km on an express road.
- Then, illuminating the engine with a lamp, determine the location of the leak and repair the malfunction.
