My Diesel Blow White Smoke. Why?

Seeing white smoke from your diesel engine can be alarming. Not only is it a sign that something isn’t right, but it can also indicate other underlying issues that may need immediate attention.  White smoke from a diesel engine often indicates the presence of un-burned fuel or coolant in the exhaust system. When these substances are not properly combusted, they create a white vapor that exits through the exhaust. Typically un-burnt fuel causes black smoke, but we have seen it cause white smoke as well.  The primary reason for white smoke is a coolant leak. When coolant leaks into the combustion chamber - and it doesn't belong there. It mixes with the diesel fuel, causing incomplete combustion. This result can be from a damaged head gasket, a cracked engine block, or a faulty cylinder head. A sure sign of a coolant leak is a sweet smell accompanying the white smoke or a noticeable drop in the coolant level.  Another common reason for white smoke is ... read more

Why did my turbocharger stop making boost?

A turbocharger is a critical component in enhancing the performance of your vehicle by forcing extra air into the combustion chamber, thereby increasing power without the need for a larger engine. However, when a turbocharger is not producing the desired boost, it can lead to a noticeable drop in engine performance and efficiency. Understanding why your turbocharger might not be making boost is the first step in solving this issue and getting back to optimal vehicle operation. Common Causes of Turbocharger Boost Issues: Turbocharger problems can stem from a variety of issues, ranging from simple fixes to more complex mechanical failures. Here are some common reasons why your turbocharger may not be performing as expected: Leaks in the Intake or Exhaust System: One of the most common causes of reduced turbo boost is a leak in the intake or exhaust system. Any leak in the intake path between the turbocharger and the engine can result in less air entering the engine, reducing boost. Sim ... read more

Diesel Fuel Injectors

Diesel engines are known for their efficiency and durability, which is largely due to their unique fuel injection system. Unlike gasoline engines that mix air and fuel before they enter the combustion chamber, diesel engines inject fuel directly into compressed, hot air at high pressure. This method, known as direct injection, allows for greater efficiency and power in diesel engines. Fuel injectors are complex mechanisms that must deliver fuel at the right moment, in the correct quantity, and in a precise pattern. This precision ensures optimal combustion, which leads to better engine performance and fuel efficiency while minimizing harmful emissions. Symptoms of Faulty Fuel Injectors Decreased Fuel Efficiency: If your diesel engine starts consuming more fuel than usual, a faulty injector could be the culprit. Engine Misfires: When fuel injectors do not deliver fuel properly, it can cause the engine to misfire, which you might notice as a stutter or hesitation when the engine is runni ... read more

Why is my diesel engine smoking?

When diesel engines produce smoke, it's usually indicative of two potential issues that can impact their performance. The first common cause is an excessive amount of fuel entering the engine without being efficiently utilized during combustion. This can occur due to issues such as a malfunctioning fuel injector or an incorrect fuel-to-air ratio. The second reason for smoke in diesel engines is related to oil consumption. If the engine is burning oil along with fuel, it can result in visible smoke emissions. This scenario often points to problems like worn-out piston rings, valve seals, or other components in the engine that are allowing oil to enter the combustion chamber. Addressing these issues promptly is crucial for maintaining the optimal efficiency of your engine. When too much fuel goes unburned or when oil is consumed improperly, it can lead to decreased fuel efficiency, increased emissions, and potential damage to engine components over time. Regular inspections and ma ... read more

Why does my CP4 pump fail?

This may be due to the CP4 pump failing. Your CP4 pump is your high-pressure fuel pump. This pump converts low fuel pressure into high fuel pressure. Your CP4 may fail due to many reasons.  The CP4 pump may fail due a lack of lubrication to the pump itself. This lack of lubrication can be from ultra-low sulfur diesel. This diesel does not have all the lubrication properties that are needed for the pump to work correctly. It can also fail due to water in your fuel system. The water will take away the lubrication properties of your diesel and this will cause the pump to fail. Water in your fuel can cause failure. Your fuel filters help to filter out the water. If you fuel filters are old, then they will not filter out the water properly.  Your CP4 pump has a camshaft with lobes inside the pump. When this component starts to fail it causes metal debris. This debris is introduced into the fueling system including your fuel injectors, fuel tank, fuel lines, anything that fuel go ... read more

How do I take care of my turbocharger?

How do I take care of my turbocharger?

A turbocharger loves clean engine oil and coolant. Having your engine oil changed at the recommended interval will keep your turbocharger working properly. Your engine oil should be changed every 5,000 miles and we always recommend using full synthetic engine oil. This will help to prevent the breakdown of the engine oil due to the higher temperatures. We also recommend a cooling system fluid service every 36 months. Over time your coolant stops protecting your engine due to electrolysis and corrosion. The corrosion-inhibiting components in your coolant break down and stop protecting your engine from damage. Some engines may need a corrosion and anti-cavitation additive.

What does a turbocharger do?

What does a turbocharger do?

A turbo charger compresses the air and forces it into the engine. When done properly this can dramatically increase the amount of power that a small engine can produce. Smaller engines are often more fuel efficient, this give you the benefit of more power and still having great fuel economy. Along with a turbocharger a few other components are needed to make it as efficient and powerful as possible. Including an intercooler, hoses, and pipes. Rapidly compressed air gets very hot, decreasing the temperature of the air through the intercooler before it goes into the engine increasing density and giving the engine more power.

How often should I change my diesel fuel filter?

How often should I change my diesel fuel filter?

We typically recommend that you change your fuel filter every 10,000 to 15,000 miles. If you think you have gotten a bad tank of fuel then we recommend that is changed again to prevent issues with your fuel system. Your fuel filter is sometimes a water separator on certain makes and models. Keeping water out of your fuel system is important. If your fuel is contaminated it can cause your fuel injectors to fail, high-pressure pump failure, low-pressure pump failure, fuel pump failure and possible engine damage. Give us a call and let us take care of you. Happy Adventures, Heather
