Control the level of the oil in the engine.
Oil system is aimed to reduce friction between rubbing parts of engine.
Besides this function oil system guarantee chilling of engine spares, remove products of fouling and wear-out, protect engine spares from corrosion.
There are cases when level of oil in case is lower than normal. We can check it with the help of the prob not earlier than 5-7 minutes after engine stopped. Normal level is the level o the oil if the trace from it on prob if between marks min and max.
If checking showed that low level of oil, add oil into case to demanded level and before find and correct possible leak of connections in engine oil system. Outside visual inspections can make sure if we have oil leak.
Increased oil pressure isn’t better than reduced one: the problem may be in viscosity of used oil, you should check its viscosity and quality and if it is necessary, change the oil. Simple case – increased pressure of oil, when you use summer oil in winter during low temperature.
