Symptoms of Curved Engine Cylinder Head

Symptoms of Curved Engine Cylinder Head – Curved cylinder heads can be a problem in a pretty expensive car. The reason is, that the repair shop offers replacement parts for one cylinder head which is quite expensive. This does not include the cost of installation and dismantling services and several other additional components. Of course, this is not what we want.

This condition is certainly a warning for us to pay attention to the cooling system. We are obliged to carry out maintenance, inspection, and replacement of car engine cooling system components on a regular basis to avoid serious damage to the engine. Because problems with the cooling system can cause big problems like this curved cylinder head problem.

Symptoms of Curved Engine Cylinder Head

The main cause of the biggest curved cylinder head is due to overheating problems. Usually, vehicle owners let and use the vehicle even though the engine is in an overheated condition. There are also many causes of overheating, such as running out of radiator water, faulty cooling fan, jammed thermostat, broken water pump, and so on.

Symptoms of Curved Engine Cylinder Head

Then what are the signs if the cylinder head of the car’s engine is curved? Well, in the following article, I will share information about the signs of a curved cylinder head that is common in car engines. Check out the information on the curved head cylinder sign below.

1. RADIATOR WATER SPRAY WHEN WE PRESS THE GAS PEDAL (RADIATOR CAP IS OPEN)

The first symptom of a curved cylinder head is that the radiator water spurts when we press the gas pedal (the engine is running). This is the symptom we see most often. The average car user who has experienced this problem will reveal this. To find out, we need to open the radiator cap first, then start the engine (do this when the engine temperature is still cold).

When the engine is running, pay attention to the radiator water from the cap hole earlier. Press the gas pedal repeatedly at 3000-4000 rpm. If radiator water spurts continuously and continues to come out of the radiator cap hole, this indicates that the cylinder head is curved.

Often we do not find the radiator water splattering, but only air bubbles that pop out of the radiator. It can also be a sign of a curved cylinder head. For this kind of symptom, the curvature of the cylinder head is not severe enough and we can still tolerate it for short-term use. Meanwhile, for long-term use, this is very dangerous. Because the small curvature of the cylinder head can cause the oil to be mixed with the radiator coolant. And of course it was very serious.

This can happen because the radiator water in the cooling system is forced by the leaking compression pressure and enters the cooling system channel. As a result, this cooling system channel becomes high pressure so that radiator water will squirt out, especially when the engine is gassed.

2. RADIATOR WATER MIXED ENGINE OIL

The second symptom of a curved cylinder head is when the radiator water mixes with the engine oil. We can observe this condition by opening the radiator cap and paying attention to the condition of the water through the lid hole earlier. If the radiator water flow is oily and contains engine oil, this indicates that the cylinder head is curved.

This can happen because the curved cylinder head will open the engine oil supply line, engine compression pressure, and the radiator water cooling system channel. When the engine oil supply line and the cooling water line meet, one of the effects is that the radiator water mixes with the engine oil.

So, if you find your car’s radiator water is oily like mixed with engine oil, this could be a sign that your car’s cylinder head has warped.

3. ENGINE OIL VOLUME INCREASED AND COLOR CHANGE

In addition to radiator water mixed with engine oil, another sign of a curved cylinder head is when the engine oil volume increases and the color changes like milk chocolate. This condition is the impact of the oil channel and radiator cooling water that are open due to the curved cylinder head.

Radiator water that should have flowed back into the radiator, instead entered the engine oil channel hole leading to the oil crankcase. With the entry of radiator water into the oil crankcase, the engine oil will increase while changing the color of the engine oil to brownish like chocolate milk.

In addition, if we pay attention to the condition of the engine, the engine will quickly run out of radiator water and the engine will also heat up faster.

4. THERE ARE OIL DROPS AND COOLANT RADIATOR FROM THE MIDDLE OF THE ENGINE

The next symptom of a curved cylinder head is the presence of drops of oil and radiator water right in the middle of the engine. This seepage appears between the engine block and the cylinder head. We can also see just below the exhaust manifold or just below the intake manifold.

In addition, the amount of seepage that comes out of the engine is very dependent on the size of the curved cylinder head. The greater the degree of curvature, the more water and oil will seep out.

5. THE EXHAUST EMITS WHITE SMOKE – Symptoms of Curved Engine Cylinder Head

The fifth sign of a curved cylinder head is when the exhaust emits white smoke. Although not the only sign, white smoke coming out of the exhaust is a factor if the cylinder head is curved.

This happens because the engine oil seeps and leaks into the combustion chamber. The oil that seeps into the combustion chamber will also burn along with the engine work. As a result, white smoke appears from the exhaust due to incomplete combustion. In addition, the smoke that comes out also has a smell like burning engine oil.

6. ENGINE VIBRATION IS POWERFUL WITH RUDE SOUND

Stronger engine vibrations accompanied by a rough sound from inside the engine can also be a sign of a curved cylinder head. The engine that vibrates strongly indicates that there has been a work failure in one of the engine cylinders due to compression leaks.

The leakage of compression causes the fuel and air mixture to be incompressible so that the explosive power after the combustion step is not maximal. When one of the engine cylinders cannot produce optimal power, the engine life becomes unbalanced and vibrates strongly. Well, this strong engine vibration also often causes knocks and rough sounds on the engine. As a result the engine vibrates accompanied by a rough sound.

7. ENGINE QUICK HEAT AND OVERHEAT – Symptoms of Curved Engine Cylinder Head

The last thing that can be a sign of a curved cylinder head is that the engine heats up quickly and overheats due to running out of radiator water. Because the cylinder head is curved, the radiator water will come out of the cooling system channel. It can come out of the engine or it can leak inside the engine.

If you find your car’s radiator water runs out quickly even though it has been filled repeatedly but you don’t find any water leaks outside the engine. So, this condition can be a sign that the cylinder head is curved.
