Everyone knows that an oil leak from a car engine is especially bad. Engine oil leaks are most common in German, American, and domestic vehicles. Whenever we open engine cover, we see that engine is full of dirt, especially on valve cover, which is oily. Then we can conclude that engine is leaking or leaking oil. Let's learn to distinguish between oil leak and oil leak.
There are not many oil stains on surface of engine
Oil stains on engine surface are not considered oil leaks or seepage. The reason is that habit of pouring engine oil is not good. If you use a funnel and wipe it down after pouring, this problem will go away. not happening.
The phenomenon of engine oil leakage
Motor oil leakage is relatively complex and hidden, and is usually caused by aging oil seals and O-rings. For example, plastic valve cover of many German brand car engines is most affected place for oil leakage. In early stage, due to aging of O-ring, there will be a small amount of oil leakage. An expensive valve cover assembly can be replaced.
Due to need for lubrication, aging timing chain cover seals can also cause oil to leak. Aging of crankshaft oil seal will cause oil leakage from both ends of crankshaft. If oil leakage occurs from side connected to gearbox, manual transmission clutch will slip due to oil contamination. Oil seepage will cause more serious losses if left untreated.
New car engine oil leakage is mainly caused by assembly and design defects. You can go to 4S store to replace oil seal; A little seepage from the stuffing box, just clean it, no problem.
Analysis of causes of engine oil leakage
Excessive engine speed will cause excessive internal pressure, and machine's internal pressure will be too high. Exhaust pressure causes engine gasket to rupture, over time engine oil leaks through gasket, and dust in engine room gets on leaking part, forming greasy oil, which looks especially uncomfortable. This is main cause of engine oil leakage.
The phenomenon of engine oil leakage
An engine oil leak means that oil is dripping or leaking in large quantities. Except for oil bottom thread seal, loose oil filter element, or oil cooler pipe leakage, it means that oil pan is broken by external force, oil filter element is broken by external force, and oil will flow out. Under high pressure, action will quickly drain from engine.
Analysis of causes of engine oil leakage
The cause of most engine oil leaks is due to aging or deformation of rubber o-ring. The most direct and effective way is to replace all o-rings! Roads in cities are congested, and stop and go need to constantly change gears, now car's gears are getting bigger and bigger, resulting in more shifts, more operating pressure and higher temperature in gearbox, which speeds up gearbox Aging and deformation of rubber fillings. There is also a small part because too much gear oil is added, which increases resistance of transmission gear. The gearbox gears work hard, and problems in gearbox will also increase, which will lead to loosening of oil seal and, ultimately, oil leakage. So refuel according to service manual.
Sudden large-scale oil leakage, for example, yesterday everything was fine, but today there is a large puddle of oil on ground, which is often caused by deformation, rupture of oil pan or failure of machine's filter. tighten. After such a problem occurs, check oil level immediately and take it to a repair shop for first time to check. If you want engine to have less oil leakage or seepage, then when buying a car, you must choose a model with reliable engine quality.
Dangers of engine oil leakage The main danger of engine oil leakage is engine oil leakage resulting in waste, and serious consequences can lead to lack of engine oil and engine damage. This is not caused by an oil leak, but by insufficient oil pressure after leak, so keep a close eye on oil level. Thanks to display of oil level in some models, it is possible to avoid situation when oil level is below norm due to ignorance, and there is also a warning light that indicates insufficient oil pressure. At this stage, everyone should be able to distinguish between an engine oil leak and an engine oil leak.
After reading editor's introduction, you now have a deeper understanding of How do you tell an engine oil leak from an oil leak? I hope editor's introduction today Difference between engine oil leak and oil leak can help everyone. If you find it useful, please save it as soon as possible. Oh, biggest support.
