Some of the most costly repairs on your engine would be from mechanical problems.
So, A neglected engine that needs to be repaired or replaced is typically the costliest maintenance issue a driver can face.
Furthermore, The heart of your car is the engine — if it fails, you’re not going anywhere.
Learning to diagnose mechanical problems can save you time and money on your vehicle.
A more expensive form of engine stoppage is a ‘blow up’, or mechanical failure. This usually only happens after a total loss of oil pressure or after extreme overheating, both of which the car’s instruments or warning lights will warn you of in time to save the engine by switching it off. If you don’t notice the warnings, loss of oil pressure will manifest itself as a heavy rattling or hammering from the engine. The onset of overheating will announce itself by a very light rattling caused by pinking or pre-ignition.
Common Mechanical Problems;
- Excessive smoke from tailpipe
- Excessive oil consumption
- Knocking or tapping sounds
- Low oil pressure
- Low compression
- Coolant mixing in oil
- Oil getting into the air cleaner and/or radiator
Mechanical Problems Can Be Caused By;
Neglecting oil changes
- Oil is the lifeblood for engines. Not regularly changing it by following the vehicle manufacturer’s recommended intervals will certainly spell doom for your engine over time. It’s important to use the proper oil type for your engine. Consequently, Many of today’s newer vehicle manufacturers have mandated the use of synthetic oils. As a result, This helps maintain peak performance and fuel efficiency. Due to the increased costs of this service, many consumers do not want to use this oil. Synthetic oil typically costs a few more dollars per quart.
Overlooking oil leaks
- On a related note, auto pros say it’s important to keep an eye out for oil leaks, especially heavy ones. In heavy leak cases, the most well-documented problem is a loss of lubrication to metal parts of the engine. As a result, causing internal tolerance wear issues and eventually premature failure. Problems that are more common occur from slower oil leaks. Because, Some of those include deterioration to the rubber engine mounts, suspension bushings and steering components.
Disregarding the engine oil light
- Most of the time engine damage is likely occurring when this light comes on. Reasons the light could come on include the oxygen sensor or the catalytic converter needs replacing. So, You would be wise to bring in your vehicle to have it diagnosed.
Ignoring the cooling system
- So, You should be flushing engine coolant every three years or 30,000 miles, whichever comes first. An engine coolant flush costs about $100 to $150, according to automotive experts . Most vehicle owners wait until a cooling system has deteriorated before making repairs. Consequently, This shortens the life of the parts that coolant is used in. An overheating engine is a common sign that your car is low in coolant. Never drive a car that is overheating, or you risk ruining the engine. Therefore, A blockage in the cooling system, loss of coolant or failing electrical cooling fans can cause overheating.
Flooding your engine
- Also, Driving through standing water or even a heavy rainstorm can potentially damage your engine. The intake manifold supplies the air/fuel mixture to the engine. If water passes through, it could cause the piston rods to bend. If the amount of water consumed is substantial enough, the engine will suffer damage from hydrolock.
