Motor oil can flow from the engine for various reasons, but any one of them should be localized and eliminated in a timely way, because the oil fasting harms any engine and reduces its resource.
The most common causes of oil leakage are as follows:
1. Issues with crankcase ventilation: A part of the exhaust gas passes through the piston rings and creates excess pressure in the crankcase. If the crankcase ventilation system is not working properly, the engine oil will be released from the engine.
2. The oil is coming out from under the valve cover. In this case, the valve cover must be replaced. It is important to tighten the bolts on the valve cover with the manufacturer's recommended effort.
3. Oil may flow from the oil filter. This is not a serious problem, it's enough to tighten the filter.
4. The oil may flow from the engine's pallet. This probably means that the pallet is damaged. It must either be attempted or replaced.
5. Oil can flow from under the crankshaft. The procedure for replacing the salamers is rather laborious. To replace them, we'll have to disassemble the engine.
There may be other reasons why the oil is derived from the engine. As a general rule, it is decided to delay connections and replace compaction.
