Common Warning Indicators Your Truck Engine Needs Repair

There's nothing more anxiety-provoking than a stalled truck, especially when Murphy's law causes the issue to occur at inconvenient times such as when you're pulling out of the driveway to go to work or when you're driving alone in the middle of the night. Often times, drivers will overlook potential warning signs, as truck repairs can be costly and there is always the hope that the  blinking "check engine" light or that odd noise just occurred by mistake. However, more often than not, these subtle signs indicate that a potentially serious issue may occur if immediate action isn't taken. Fortunately, understanding the common warning indicators of a truck engine in need of repair can help to ensure prompt detection and repair, allowing truck owners to save money and time in the long run.

Blue or White Tailpipe Smoke

Blue smoke emitting from a truck's tailpipe typically indicates that the engine is burning oil at an excessive rate. This can be caused by several factors that include broken valve guides, worn down cylinder heads and damaged piston rings at the bottom of the engine.

White smoke is a common symptom of a broken head gasket that causes coolant to make its way into the combustion chamber. In most cases, replacing the damaged parts can remedy the issue, but it is always best for drivers to take their trucks in for a full inspection to ensure an accurate diagnosis and proper repair. 

Loud Noises 

While cars and trucks are known to make all kinds of noises that are not always connected to the engine, a loud, banging noise or a knocking sound that becomes louder during acceleration may indicate bearing failure at the bottom end of the engine. Fortunately, this issue can usually be easily repaired and not cause irreversible engine damage, as long as it is detected and repaired as soon as possible. 

Rapid Loss of Engine Power

While it is common for truck engines to gradually lose strength and power over time, a loss of engine power that occurs rapidly can indicate a failed engine component, especially when accompanied by noises. Drivers may also notice that their trucks run rougher than usual during this time. This issue should never be ignored, as immediate truck repair is required to prevent severe, irreversible engine damage. 

Know the Signs, Save Money and Time

Irreversible truck engine damage can be frustrating and costly. Understanding the warning signs of potential damage can help truck owners promptly detect potential issues and seek immediate repair (from professionals such as JP's Truck Service).
