The 5 Most Common Hyundai 2.0T/Theta Engine Problems

Is the Hyundai Theta engine the same as the Hyundai 2.0 Turbo engine?

1. Your Engine Suddenly Failing Could Endanger Your Life

Your engine is probably one of the most important parts of your car that you often forget about.

Since the engine isn’t always in view, it can be easy to forget how important it is.

So finding out your engine is having problems does cause some serious concern.

What Is The Engine Failure?

Having engine failure is not specific to only this engine. Many engines from different companies can experience the issue, so it’s not too much to be concerned about.

However, it can lead to much bigger issues concerning your car, so you might be better off acknowledging it earlier on.

The engine mainly fails when the oil flow to the motors rod bearings is lessened.

The lack of oil flow can cause the bearings to wear down much faster than they would before and eventually seize.

Engines tend to fail more when:

  • You neglect to check them every once in a while.
  • There is an issue with the oil being put in them.
  • Something is wrong within the operation, but you don’t pay any heed to it.

Why Does It Matter?

Engine failure matters because it can show us how everything else is deeply affected in the car.

Engine failures can cause excessive oil consumption, as you already know that the oil present is failing to reach the bearings.

Not only can that happen, but the customer hears a strange knocking sound from the engine itself.

The indication of any extra noise coming from the engine is always a topic of concern, as you can imagine.

The motor’s overall performance is always seen to be lacking since the motor doesn’t have enough oil in it.

Poor performance is not a part of what the 2.0T motor offers, so if your motor performs poorly, you might want to get that checked.

How To Fix The Problem

If you want a much cheaper route to fixing your problem, you might want to replace the whole engine. Repairs for the motor can get a lot costly since they can be frequent.

The whole choice of the fix is completely up to you, but personally speaking, I believe a new engine would cost you a lot less money and benefit you in the long run.

2. Carbon Buildup Is One Of The Biggest Problems You Might Have

The problem with carbon build-up is mainly the neglect that leads up to it.

If you’re a person with a car, essentially, you should take care of the car, but overall this is not the case as to how people act with their cars. Hence carbon buildup can be a real issue.

Carbon Buildup Explained

By definition, carbon buildup is the deposits of oil that happen along with the intake valves and ports of the motor.

Because so much of the oil is flowing around in the engine, the oil is bound to collect in certain areas. Think of it like the clogging of a human body’s arteries from oil intake.

The same thing applies to the Hyundai 2.0 Turbo engine, except the engine does not have a way to clear such a mess out on its own.

The carbon build-up can be a real issue for many people because it can be really hard to tell if any build-up has been done or not.

Understanding The Problem

While you may think a little oil build-up in your engine is not the worst thing that could happen, there are so many ways that your engine is affected.

With the beginning of misfires within the motor, your entire car could be in a lot of danger.

Rough idle is also a common indicator of carbon buildup, although you may not always link it to such a problem.

Your car may even begin to stutter and hesitate, which means you’ll have such a hard time making the car start. Power loss within the motor is also very common.

All of these symptoms can be linked to other such problems, but when most of them are seen happening together, you might need to pay a little more attention because the indication of carbon buildup might be given to you.

You need to understand carbon buildup because:

  • You might figure out what is wrong with the car.
  • It will be easier to save the car from damage.
  • Prevention becomes even easier.

What Happens When You Don’t Pay Attention?

Paying attention to your car is important, so your car can become irreversibly damaged when you don’t pay attention to the carbon build-up.

To prevent this from happening, you need to focus on removing the carbon build-up, which can be done by walnut blasting.

The process includes blasting the shells into the intake ports to remove excessive, unnecessary buildup.

3. Excessive Oil Consumption Is A Terrible Thing To Face

Oil is more precious than gold at a time so having a problem with the oil being consumed in your car is an actual thing.

While you may think the issue is not as big as it means, the expenses of having to refill your oil tank constantly would be enough to bring anyone to tears.

Problem With Oil Consumption

As you can imagine, there are many things wrong with having excessive oil consumption.

Oil is important for any engine to work correctly, and if you do not have oil in your Hyundai 2.0T engine, that is also a way for the engine to begin to fail.

However, if your motor takes up more oil than normal, it can be a serious cause for concern.

Oil consumption for each kind of motor has a significant difference, but one thing you should know is that no motor finishes oil that quickly.

Oil consumed in a large amount is dangerous because it causes the customer to come into serious financial crises.

Oil And Your Engine

The best way to describe the issue lies in understanding what oil does for your motor and how excessive oil can ruin your motor.

Oil is a way for the motor to function without extra effort, so it helps the motor in being able to move the parts and everything without extra effort.

If there is heavy oil consumption, the 2.0T engine may start displaying signs of smoke coming from the exhaust.

Alongside that, because of the excess oil, you might end up smelling burning oil because the motor’s heat will cause the oil to burn.

Oil is used in the engine to:

  • Have parts moving much more smoothly.
  • Guarantee more power for the motor to work.
  • Help in the easy function of many bits.

Solutions To Consider

Keeping in check with how much oil you put in, how much has been used, and how much time it took is a great way to keep the overuse in check.

Make sure to get proper maintenance of your car done every once in a while to know how much your car uses the oil you put into it and when excessive is being taken in.

4. Having Oil Leaks Could Harm Your Engine In Multitudes

Oil leaks are another part of the engine problems that cause more damage than you would think.

Your engine suddenly leaking oil is never a good sign, so make sure to get something like that checked immediately.

Oil’s Purpose In The Engine Itself

You know that oil is used to power the motor in your car but did you know that oil is also meant to be the lubrication for moving parts?

The engine is in constant motion, so lubrication makes it even easier for the motor to move.

The oil can also be the cooling agent in the motor to make sure that the motor isn’t overworked.

The Dangers Ahead From Oil Leaking

You might be thinking about what dangers lie in the oil leaking. The simple answer to that is the main leak shown within the engine.

Your Hyundai 2.0T engine can display a very major leak that can light on fire if not taken care of.

The amount of oil wasted is bound to bring about oil loss which can never be good for the car. You might also notice a very strong and unpleasant burning smell.

Why Understanding Is Important For Your Car

Oil leaks need to be understood because your car can be in danger if you do not fix the problem at hand.

With the whole situation comes the responsibility of taking care of your health, so make sure to get your car maintained as often as possible.

While the car is maintained, please make sure:

  • Not to use the car excessively.
  • To change the oil if it seems of poor quality.
  • Keep checking for any problems.

5. Problems With The Camshaft Can Arise Because Of Various Reasons

Lastly, understanding the camshaft is the most important thing. Your camshaft ensures that fewer problems occur within the engine.

What Is The Camshaft, And Why Is It Important?

A camshaft is a rotating object meant to control the input of fuel towards the engine and the output of exhaust fumes within the engine.

The camshaft helps balance out the motor’s general functions and balances out the temperature of both the inside-outside of the car.

The camshaft has the job of helping valves open and close, so you might consider it a cover.

Reasons For The Problems That Come Up

Several reasons cause the issue. Camshafts can fail because of normal wear and tear, but they can also get ruined because of excessive damage.

A bad camshaft can cause misfires in the motor, and the motor involved can be shut down because of the damage done to the camshaft.

Generally, using the camshafts, we can make sure that everything is working perfectly within the motor, but if the camshafts fail, we do not have any good output from the motor itself.

Camshafts might be affected due to:

  • Extreme misuse and abuse.
  • Lack of maintenance.
  • A change in how you drive your car.

Preventing It Further From Happening

Changing the camshafts is the best way to deal with the issue, and it is also the simplest way to deal with such an issue.

So make sure that you keep checking your Hyundai 2.0 Turbo engine parts regularly to ensure the best ways to save them from getting ruined.
