Newer engines typically last 200,000 miles before a replacement is needed. Older engines, meanwhile, last about 100,000 miles or between 5-7 years. When you notice signs of wear and tear, it’s time to take your vehicle to a mechanic for an engine replacement. Once replaced, there are a few common problems that may occur. These issues are outlined below.
Most Common Problems Following An Engine Replacement
Because a car engine replacement is such a complex process, sometimes unwanted problems can occur as a result. Below are a few of the most common problems following a replacement. Drivers should not ignore these issues.
1. Car Won’t Start
This is actually the most common issue drivers face after an engine replacement, but you should not worry! The reason this may be happening is because there is a compression issue likely due to an error in the ignition timing or faulty timing belt.
In this case, you can contact the mechanic to see if they will use a compression gauge test. The problem could also be related to the spark plugs. They may be filled with dirt and carbon following a replacement. Replacing or cleaning the spark plugs will fix this problem.
2. Strange Noises
Depending on the type of vehicle, the sound of the internal combustion engine will either be smooth or loud. However, any unusual noise like a clicking or knocking can be a cause for concern.
A lack of oil or dirty oil can cause unusual noises by hindering the operation of the wheel. The engine could suffer damage if not checked and/or fixed in a timely matter.
3. Emitting Smoke
Another common occurrence following the replacement is unusual smoke coming from the back of the vehicle. Drivers can tell how severe the issue is by identifying the color of the smoke. Black smoke means the car is operating with an excess of air and fuel.
This can occur due to dirty or clogged air filters that do not allow enough air to reach the correct mixture ratio. If the engine is burning with lubricating oil and there is leakage, you will notice blue smoke. If left unrepaired, the car will consume too much oil and ultimately damage engine components.
4. Electrical Issues
Other common problems include blown fuses, faulty sensors, or other electrical issues. Electrical troubles typically occur following an engine replacement.
The replacement process involves reconnecting and disconnecting electrical parts within the vehicle. If this is not done properly, it can impact the car’s electrical system.
5. Car Overheating
The temperature indicator lights or temperature gauge are on in all vehicles, old and new. When the engine starts properly, the clock hands from the starting line will slowly increase to the middle. If the clock hands quickly peaks while the vehicle is in motion, this means the engine is not working properly. This is a serious issue that can cause the engine to explode.
Turn the car off for an extended period of time to let the engine cool down. Take the care to your local mechanic as soon as possible for a diagnosis.
