An engine is the heart of any vehicle. So there is nothing worse when the core of your car fails to perform due to engine trouble. Engine failures range from moderate to severe, and it’s best to get them fixed in their initial stages to prevent further damage.
Here are some common symptoms of engine trouble you may observe:
- Rattling noise from the engine
- Engine oil drips on the ground
- The engine turns over but doesn’t start
- The temperature gauge reads hot
- Engine stalls while driving or idling
- Bubbling noise after engine turned off
- Coolant leaking
- Black, blue or white smoke from the exhaust
Common Car Engine Problems
What is a Rod Knock
It a knocking sounds that come from the engine. Its caused by the damage to the rod bearings. When the connecting rods inside the vehicle have a lot of clearance, their movement is affected. So, when the piston changes direction, metal comes in contact with other metal producing the rapping noises. This is “rod knock”. These symptoms are aggravated with increased load and speed.
Causes of Rod Knock
The leading cause of rod knock is then the engine has an extremely low supply of oil. This reduces friction and causes the metal bearings to grind away at crankshafts until they are loose. Even a little bit of play causes it to sound like there is a bunch of hammers in your engines knocking away at each other.
Other causes include:
- Defects in the main crankshaft bearings
- The broken tensioner of the timing belt
- The cracked flywheel of the car
- Failed air conditioning compressor
- Worn down water pump bearings
- Damaged alternator rotor bearing
Repairing rod knocks is a costly process; most people prefer to get rid of their vehicles rather than repairing them. Their repair costs can be anywhere from $1,100 to $4,500 more or less, considering labour and part costs.
What is Engine Overheating?
Overheating happens when the car’s engine becomes too hot to operate. If this happens, to prevent further damages, you should immediately pull over and start the heater, which can help to cool down the engine while you call the towing service.
Causes of Engine Overheating
- No coolant or too little coolant in the vehicle
- There is a leak in the cooling system of the car
- Broken water pump
- Radiator fan issues
- Not enough oil in the engine
- Failure of the thermostat can prevent coolant from flowing in the engine
- Blockage, rupture, or leak of coolant hoses
- A clogged heat exchanger may prevent coolant flow into the engine
The more the engine overheats, the more damage it causes the engine. Therefore you can lower the cost of engine repair if you stop the car at the first sign of overheating and get it fixed. Usually, the rates of repair are as follows:
- Replacing water pump can cost $500 to $1,500
- Changing the radiator can cost $300 to $500
- Engine replacements $4,000 to $6,000
Engine Oil Leaks
What are Engine Oil Leaks?
If you find a pool of black liquid beneath your vehicle, it’s a sign of an oil leak in your car. Another sign is engine oil tends to drip on the hot exhaust leading to a putrid smell on its way to the ground, which can provide another symptom to identify a leak in the system.
Causes of Engine Oil Leak
Many causes can lead to an engine leaking oil, including problems with cylinder head gasket, crankshaft oil seal, oil pan gasket, valve cover gasket, PCV valves, engine oil cooler, etc.
Gasket material tends to deteriorate over time, and so do the rubber seals in the car, so when they break, causing oil to enter the wrong side and causing leaks, These seals can also be blown out by too much engine pressure.
If there is a problem with the PCV valve, it can be replaced with as little as $12, but if broken seals in the gasket cause the leaks, it costs upwards of $1,500. And the bad news is if one seal is damaged due to age, others will follow, and it can be a costly repair to do.
Engine Won’t Start.
Causes of Engine not starting
There can be many causes for an engine not starting, such as electrical or mechanical reasons. So, if your engine is turning, but the car is not starting, it can be due to no fuel, bad fuel, broken wiring, no sparks, blown fuses, etc. But if your engine is not turning, there can be a problem with your starter or an electrical issue.
It once again depends on the type of damage that has caused the engine from working. If there is an electrical issue such as a blown a fuse, a repair can be $1, but if there is a problem with the fuel system or starter, it can cost $1,000 to $2,000
Broken Timing Belt
What is a Broken Timing Belt?
The timing belt is a rubber belt that ensures that the camshaft and crankshaft work in sync. When they work together in perfect sync, they are able to lower and raise the piston. Which in turn allows the combustion reaction to happen right on time to make the vehicle move.
Causes of broken Timing Belt?
When the timing belt ages, its rubber breaks down and cracks and stretches. If there is an oil leak, it can be worse, and the rubber may swell and eventually, it will break with regular wear and tear.
Maintenance of timing belt is much cheaper than repairs. A simple timing belt replacement can cost you $300 to $500. But if it breaks, it can lead to severe engine damage and hence replacement,
Blown Head Gasket
What is a Blown Head Gasket?
A blown gasket is when the seal between the cylinder head of the car and the engine fails. The failing of the head gasket can lead to coolant leaks, oil leaks and leaks of gasses from the combustion chambers.
Causes of Blown Head Gasket?
Overheating issues mainly cause gasket failure, more specifically, repeated overheating. So to prevent it, it’s best to ensure the car’s cooling system is in good condition.
A typical head gasket repair cost is $1,500 to $3,500. But if you have run your vehicle for a long time with a blown gasket, you would need to replace the cylinder heads, but that’s only after severe damage.
Cracked Engine Block
What is a Cracked Engine Block?
A crack in the engine block occurs when contaminants make their way into the metal during the manufacturing process. These poorly made clock leaks, causing the antifreeze to mix with engine oil resulting in smoke and foul smells. Other signs include:
- Engine overheating because of antifreeze leaks
- Discolouration of antifreeze or oil
- Fluid leaking from the engine
- Poor performing engine
Causes of Crack Engine Block?
The two main causes of cracked engine blocks are overheating and water pump failure. These two are interconnected as an issue with the coolant can cause the overheated part of the cylinder to expand, which leads to a crack in the block, and water pump failure can prevent the flow of coolant, which again leads to overheating.
Engine block repairs are impossible, and you would have to replace the engine to keep your car running. A used engine can cost you around $2,500, while if you purchase a new one, you can expect to pay $4,000 to $8,000 for it.
What is Seized Engine?
A seized engine is when the electric components of the car, such as radio, AC, etc., work, but still, the engine will not start. And there will be constant knocking and clunking sounds when turning the engine.
Causes of Seized Engine?
A few of the common causes that lead to a seized engine include:
- Low oil levels
- The car became repeatedly overheated
- Connecting rod and crankshaft because heated due to friction
The repair cost for seized engine ranges from $3,000 for a used engine replacement to $8,000 for a brand new engine.
Keeping your vehicle running in perfect condition is all about maintenance. So it’s best always to check your owner’s manual to see when an item needs replacements. This way, you would run your vehicle without any trouble and save money in the long run.
How to Sell a Car with a Bad Engine
If you want to sell your car with a bad engine, you can either sell to a scrap car buyer or sell each part of the car separately.
If you choose to sell the car part separately, you would have to hire extra help to help you remove and verify the parts and advertise them online. This method is very profitable but time-consuming.
Working with scrap car buyers, on the other hand, is a little less time-consuming. You can sell your unwanted vehicle within a day or two with them, but these businesses’ cash payment is usually quite less.
