Common Engine Problems

Hard Starting

Diesel engines rely on cylinder pressure to ignite the fuel and generate power; additional pressure in the cylinder can cause a hard start. Hard starts can happen due to low battery, glow plug malfunction, obstructed fuel filters, and lines, and other such problems. If your car doesn’t start properly or experiences a hard start, you need to take it to your diesel engine repair mechanic to correct the problem immediately.

Defective Glow Plug

Defective glow plugs can cause a number of problems so if your experience things like engine misfires, hard starting, black smoke, and full shutdown, there’s a possibility that the glow plug is damaged or doesn’t work well. The glow plug is when of the first things the diesel engine repair mechanic would test when you bring in your car for repair.

Thickened Diesel

Diesel is more susceptible to thickening than gasoline, especially during the winter. Cold temperature can turn it into something gel-like that doesn’t flow smoothly through the engine. You’ll need a good and experienced mechanic to handle the problem for you otherwise your car simply won’t start for a long time.

Thickened Or Wrong Engine Oil

Over time, the engine oil can also become thick and viscous. In such cases, our mechanics recommend switching to lighter engine oil that would suit your vehicle better. Our diesel engine repair mechanic would recommend the best one for you.

Black Smoke

Diesel cars sometimes emit black smoke and this can happen for a number of reasons. Usually it happens because of an imbalance in fuel to air ratio with too much fuel and too little air in the engine.

This approach is faster and might be suitable if the existing transmission is severely damaged or outdated.

A clutch in a car is a mechanical component that facilitates the engagement and disengagement of power between the engine and the transmission. It allows the driver to shift gears and control the transfer of power from the engine to the wheels. The clutch consists of a clutch pedal, which the driver operates, a clutch disc, and a pressure plate.

Can I drive with a slipping clutch?

Driving with a slipping clutch is not recommended as it can lead to further damage to your vehicle’s transmission.

Transmission re-buld or transmission replacement?
