Too Much Black, Blue, or White Smoke
When it comes to your diesel engine. Too much smoke under your hood or from the tailpipe is always a good indicator of something wrong. Different types of smoke can be great indicators of different issues with your diesel engine.
If your diesel truck is emitting too much black smoke, this can be an indicator of an imbalance in the fuel-to-air ratio. Usually, this means your truck is burning up more fuel than air during its combustion process, causing the truck to release more black smoke. This can be an indication of problematic fuel injectors, a malfunctioning fuel injector pump, or bad air filters.
If your truck is emitting blue smoke, this can indicate that your diesel engine is burning oils. This can be an indicator your oil is leaking into other parts of your truck, which can be a very serious problem.
White smoke, on the other hand, means your truck has leaked into the engine, causing it to burn coolant along with fuel. Not addressing these issues soon can cause even more damage to your engine.
Hard To Start

A regular oil change is extremely vital for the health of your vehicle. This is especially true for a diesel truck that has been idle for a long period, say maybe throughout the winter. If your diesel truck stays idle for a while, the oil can get oxidized. This means that air gets into your oil causing bubbles into it and causing contamination. Oxidized oil is a less effective lubricant.
When your truck does not have enough lubrication, this can cause a lot of damage to the moving parts due to increased friction, which can eventually damage your truck engine even more. Thus, you should take your vehicle to your truck for an oil change. Especially if it has gone unused for a while.
Your truck overheating can be a clear-cut sign that your diesel engine has a problem. There are so many reasons why your engine is overheating. Perhaps you have a coolant leak.
