5 REASONS WHY YOUR CAR MAY LOSE OR LEAK OIL

 Oil leaks and losses are one of the most common reasons drivers invite their car for inspection. It can be a tiny hole in a gasket, an obvious shock from a bad seal or a leak from a variety of origins. In any case, it is important to identify the source of the oil leak in your car and diagnose what repairs are needed to correct the leak and prevent your oil from leaving the point where it's most needed.

5 major reasons why your car may leak oil:


1.  BURNING OIL

As the heart of your engine is the combustion chamber, where all the magic takes place. Normally, oil is kept out of this chamber by piston rings and valve seals. If something happens to your rings or valve seals, your oil will enter your combustion
chamber, if your rings or valve seals are leaking, you may find that your oil is disappearing. However, if bad gaskets or other holes are outside the engine, you probably will not see oil on the ground or the engine. This is because oil from a small leak of this nature, such as only a partially warped piston ring or just a defective valve, is likely to be burned in the combustion process. If the problem becomes chronic and multiple rings or valve seals go bad, the car will probably stop running as oil overflows the combustion chambers and removes the car's ability to process fuel.

Unfortunately, if this happens, you will have to incur significant repair costs, especially if you need to go to a store, which is highly recommended for any vehicle you can not risk.

2. WRONG INSTALLATION

While it is much more common after a DIY, even professional mechanics make the mistake of incorrectly installing one of the many seals that hold the oil in the car where it should stay. The most common reason why this happens and is overlooked is that someone has tightened an oil sump gasket or valve cover gasket too tightly or has not evenly distributed the tightness throughout the gasket. In this case, the seal can be "squeezed", creating an oilfield. And depending on how the seal is not properly tightened, this simple mistake can only lead to a "hole" or become a pretty big barrage. Substituting an oil filter can do virtually the same thing, as it can be over tightened or even skewed too much than you think.

It is also not uncommon for a new gasket to be installed before all surfaces have been properly cleaned of any old seal remnants. This can lead to uneven seals and leaks, just as if you had tightened them too tight corner.
As long as you keep a clear head and remember that it happens to everyone more often than you can imagine, you or your mechanic can immerse yourself again and have the sealing problem corrected.

3. HOLES

However, it is much more common to find holes in older seals or gaskets in areas of higher temperatures and stresses, e.g. For example, in the head gasket or in the rear main seal, which should prevent oil from getting into the transmission and transmission fluid from mixing into your engine.

Unfortunately, gaskets are not the only part of your engine that can make holes. It is quite common to accidentally puncture your sump cover by accidentally poking a hole in the new oil filter you just had trouble installing.

If you're really unlucky, you may see a valve stem through the top of your valve cover, the bottom of your sump, or even shoot through the side of your engine block. Such disasters are never cheap to repair, but they are almost always intriguing to investigate.

Luckily, most holes in gaskets only arise because the gasket is old. They can often be temporarily sealed with a liquid gasket until you can change them

4. CYLINDER HEAD TRAUMA

A much rarer source of leaking oil is a cracked cylinder head or engine block. Sometimes you do not even see oil on the engine or on the ground. This is usually because the oil gets into your coolant system and not to the ground where you would expect it. Regardless, you can often check this diagnosis in both cases by checking your oil and coolant cap. One or both are muddy brown and probably smell of syrup and oil.

5. OIL SPILLAGE  FROM DIPSTICK TUBE

This can happen if there is oil pressure in the engine. Do you remember the old days when every car had an oil pressure gauge on the dashboard? Today, a light shines when the oil pressure is low. Thus, if the dipstick does not ensure the pressure of the oil in the engine , the oil will be squeezed out of each low pressure area
