Diesel Engine Repair Diagnostics

It all starts with a series of in-depth diagnostic tests. We use a combination of computer-driven diagnostic technology and years of established knowledge of diesel engines to provide a comprehensive overview of your engine’s performance.

Diesel engines tend to be overbuilt so they can withstand the extreme compression pressure used to power them. This means that, on the one hand, diesel engines are built to last—and to take a lot of daily abuse. On the other hand, the extreme pressure requires absolute precision in both construction and maintenance. From air intakes and compression ignition to high-pressure cylinders and turbochargers, our diagnostic procedures are designed to test every component on your engine and to determine even the slightest problem.

If there’s an inefficiency or worse, damage, we’ll find it. We’ll fix it. We’ll get you back on the road, fast.

However, these are just a sampling of the work we do at Cien Motor Sports. If your diesel engine is giving you problems, bring it in for servicing.

What Happens When an Injector Goes Bad in a Diesel Engine?

When an injector fails in a diesel engine, it can lead to various performance issues affecting its efficiency and operation.

Here are the symptoms of a bad injector:

• Increased fuel consumption: A malfunctioning injector can lead to an improper fuel-to-air ratio, resulting in excessive fuel use.
• Poor engine performance: You may experience a lack of power, hesitation during acceleration, or rough idle due to uneven fuel delivery.
• Excessive exhaust smoke: Bad injectors can cause incomplete combustion, leading to visible black or white smoke from the exhaust.
• Engine knocking or tapping: A faulty injector may introduce fuel irregularities that cause knocking sounds, indicating improper combustion.
• Check engine light: Modern diesel engines often trigger a diagnostic trouble code that activates the check engine light when injector issues are detected.

Should You Clean or Replace Diesel Injectors?

Consider the injector’s condition when deciding whether to clean or replace diesel injectors. A cleaning might suffice if you notice symptoms like poor performance or excessive smoke. This process can restore optimal fuel flow and improve engine function.

However, replacement is better if cleaning doesn’t resolve the issues or the injectors show signs of wear. New injectors can enhance efficiency, reduce emissions, and protect your engine from damage caused by poor fuel delivery.

What Does a Turbocharger Do on a Diesel Engine?

A turbocharger plays a critical role in enhancing the performance of a diesel engine by forcing more air into the combustion chamber, which allows for a more efficient fuel burn. This process creates more power and torque, improving acceleration and towing capabilities.

Turbochargers can increase fuel efficiency by utilizing exhaust gases to spin a turbine that powers the compressor rather than relying solely on the engine’s power. This allows for improved fuel-to-air ratios and reduced emissions, making them an important component of modern diesel engines.

What Happens When a Turbo Fails on a Diesel?

When a turbo fails on a diesel engine, you’ll notice a significant drop in performance and power.

Common signs include:

• Loud screeching noises
• Blue or black smoke from the exhaust
• Loss of power and acceleration

If left unaddressed, driving with a failed turbo can cause extensive damage to the engine.

Do Diesel Engines Need Oil Changes More Often?

Yes, diesel engines need oil changes more often than petrol engines. Generally, diesel engines produce more soot and contaminants due to their combustion process, which can degrade oil faster. Changing diesel engine oil every 3,000 to 7,500 miles is recommended, depending on your driving conditions and the manufacturer’s guidelines.

Always pay attention to your engine’s oil level and condition, and schedule changes promptly to avoid potential complications down the road.

Are Diesel Engines Ruined if They Overheat?

If your diesel engine overheats, it doesn’t necessarily mean it’s ruined; ignoring the problem can lead to severe damage. When temperatures soar, components like the head gasket can fail, which could result in costly repairs.

Turn off the engine immediately if you notice overheating. After it cools, check for any visible coolant leaks or low levels. The problem could be with the radiator or water pump if there is no visible leak. It’s best to have a mechanic inspect and diagnose the issue.
