You love your diesel truck, but lately, it’s been giving you problems. There’s no need to worry. Trojan Auto Care works on all types of engines including diesel engines. In fact, we don’t mean to brag, but we are experts when it comes to these amazing pieces of machinery. We fix problems with diesel engines every day. Here are the most common issues we come across.
Starting/Power Troubles
Every diesel engine cranks a bit before it starts, but you should never have extreme difficulty getting your diesel engine to fire up and run. Usually, difficult starts are just a sign that your diesel automobile is overdue for maintenance, but it can also be a sign of fuel system problems. Power loss will also accompany fuel system problems. The most common things we fix are clogged fuel injectors, dirty fuel filters, loose throttle linkage issues, and excessive engine lubrication.
Exhaust/Fuel Problems
Diesel fuel has many advantages over gasoline, but one of the disadvantages is that it gets contaminated very easily. Diesel fuel is thick and energy-dense. This means it produces more power per gallon but also hangs onto contamination. Glycol, soot, and water commonly contaminate diesel fuel and create fuel problems. This can leave you with excess black exhaust, as can a rich diesel fuel mixture that is starved of air. Air filters, fuel injectors, EGR valves, and faulty turbochargers can all cause rich fuel mixtures.
Oil Oxidation/Incorrect Weight
Oil oxidation is a common problem in a diesel truck that has sat around without being run for an extended period of time. Oxidation means that air has gotten into the oil. This causes the oil to bubble and prevents it from lubricating your engine the way that it needs to. This, naturally, damages your engine. Another thing that can damage the engine is putting the wrong oil viscosity weight in there. Always use the correct viscosity weight when changing the oil.
Too Much Noise
Finally, your diesel engine should never make too much noise. If you hear excess noise or knocking, this usually signals there’s something going wrong with the fuel injectors. They could be clogged or leaking, and this reduces your diesel engine’s performance because it causes an imbalance in the engine’s compression. Yes, diesel engines can be noisy, but that noise should not be overbearing.
