These Are 6 Signs Your Car Needs An Engine Repair




The engine is the heart of your vehicle, giving your car the necessary power it needs to operate correctly. When the engine is damaged, it will significantly affect your car’s performance. Fortunately, you can save yourself time and money by quickly diagnosing engine problems before they cause more harm to your vehicle. 

Below are the 6 signs your car needs an engine repair

1)The check engine light turns on
Dashboard warning lights are your car’s way of alerting you about problems it detects via its On-Board Diagnostics (OBD) system.
While the check engine light can be triggered by many different issues, many of them are directly related to engine performance,and ignoring the light will only lead to greater problems.

2)Your car is making strange noises
A knocking noise coming from your bonnet is a sign of a dying engine. This noise could be caused by wear or damage to your engine’s mechanical parts such as pistons, bearings or other moving parts. Other noises you should look out for include popping, spitting and backfiring from your exhaust.

3)You experience a loss of engine power
Your car engines will struggle to run at their usual level if there is an internal problem. The vehicle may stall, shake at high speeds or struggle when climbing a bridge.

4)Excessive Smoke from your exhaust
There are several reasons why your exhaust could be producing smoke. The colour of the smoke can give you an idea of what is causing the problem.

If the smoke is black, it means that your engine has incomplete combustion which leads to burning too much fuel. This could be due to damaged fuel injectors, malfunctioning sensors, damaged air filter and clogged fuel return line.

Grey smoke may come from a stucked pcv valve, problems with your transmission fluid and excessive oil consumption.

Dark blue smoke means that oil is leaking into your engine’s combustion chamber. This can be caused by worn out piston rings, damaged valve seals and other worn or damaged engine components.

5)The engine is running roughly
A struggling engine will often shake or lose power as the revs increase. A few common solutions for this may be to replace the spark plugs, replace your ignition coils, check your fuel pressure, clean your air flow meter or give your engine a tune-up.

6)Your car produces oil patches
If you notice puddles of oil under your vehicle, this is probably a result of a leak in your engine. As the oil depletes, more friction will occur in your engine, generating excess heat. Oil leaks are common from engine oil seals, and sump plugs/sump plug washers.

You don’t want a costly car repairs due to engine troubles. Learn to notice the signs of engine problems by seeing, hearing and smelling what’s going on with your vehicle while you drive it.

    Your statement about how you should pay attention to your engine functionality because it is the heart of your car that affects your vehicle’s performance caught my attention. I also like that you enumerated each sign of a car engine repair. My son tried to use my car today since his car is under repair. He noticed that there is a strange noise coming out from the engine whenever he tries to start it. He ended up commuting because I’m afraid that there must be something wrong with the engine. I take into an account how important engines are, so I’ll make sure to visit an auto shop soon for repair.
