5 Causes Of Car Engine Low Compression

Another familiar problem that your car may experience is car engine low compression. Among numerous problems that may relate to this condition, there are general give causes of car engine low compression. How can we tell a car suffers from it? If car encounters this condition, you may notice it from misfire once you try to start the engine. It is because compression stimulates the fuel and air to combust. Therefore, if there is no sufficient compression, the fuel and air combustion will not be optimal so the generated power is low.

Cars that encounter this problem show other symptoms besides misfiring when starting. You will eventually notice the engine power gradually gets weaker. Some types of cars will produce white smoke which comes out from the exhaust pipe. White smoke is a sign that there is oil which is combusted along with fuel and air. You may also notice the engine oil runs out quicker than usual. As previously stated, this is because the oil gets into the combustion chamber, mixed with fuel and air. Last, indication of car engine low compression is engine makes rough noise.

It is important to acknowledge oneself about causes that may trigger low compression on car engine. Hence, you will be able to seek proper fixing when going to the mechanic. There are some factors which possibly make the compression lower than the standard. However, these are general five causes of car engine low compression you may find in your vehicle.

Problem on Piston Rings

This condition appears in certain period of use. Worn-out piston rings will make small friction that will be more noticeable from time to time. This damage will bring impact in making car engine low compression in relatively long period of time.

Bad piston rings can also be caused by overheating. Excessive heat makes these part broken so they will no longer be able to seal carbon gasses inside the cylinder. The leak gasses will pass through the rings.

Therefore, though you have applied proper maintenance for your car, there is still a chance for component replacement as they naturally loose performance because of regular, permanent use.

Valves Leakage

Another cause of car engine low compression is valves leakage. These valves are responsible for the air and fuel to go into and come out of the valves for combustion process. One of the trigger of valves leakage is overheating. It causes the valves release gasses beforehand the natural process so the compression is low and the engine is weak.

Bad Head Gaskets

The function of head gaskets is to adjoin cylinder block components to the head. If these parts fail to function properly, it leaves a gap and compression leakage will occur. Compression will not be optimal because of the leakage and result weak engine.

Valves and the Stand are not Properly Adjusted

Another general five causes of car engine low compression is poorly adjusted valves and the stand. This condition results leakage and later causes compression low. It can be fixed by doing adjustment on these parts so there will not be gap between them.

Broken Piston

The last general five causes of car engine low compression is broken piston. Damaged piston is shown by holes on the component. These holes are result from excessive heat from engine overheating that get into the piston making spot forms. These hot spots will later burn holes through the pistons. Through these holes, leak gasses will pass and low compression occurs.
