One question that we get asked here at United Diesel Repair frequently is what are the problems that diesel engines have? As with any piece of machinery, diesel engines can be prone to common problems if they are not cared for properly. The best way to ensure you don’t have any problems with your diesel engine is to maintain it per the manufacturer’s recommendations. This being said, we are vastly experienced in diesel engine repair, including fixing the common problems below.
Hard Starts
You will have difficulty getting your diesel engine started if you do not take care of it. In fact, hard starts are an indication that the engine needs to be serviced. Bring your diesel vehicle to our shop if you are having difficulty getting it started.
Power Loss
Power loss generally points to a problem with the fuel system. For example, if the fuel filter or fuel injectors are clogged, you will lose power in your diesel engine. You will also lose power if the throttle linkage is loose or you have excessive lubrication.
Fuel Contamination
You may also have power loss, difficulty accelerating, and other engine performance problems if your diesel fuel gets contaminated. Many things can contaminate the diesel fuel, but common culprits include water, soot, and glycol.
Oxidized Oil
The motor oil in your diesel engine will also oxidize if you leave the engine sitting for months without starting it. Oxidized oil is filled with air bubbles that can damage your diesel engine if you drive the automobile.
Excess Exhaust
You will see a little bit of exhaust flowing out of your diesel vehicle’s tailpipe, but you should never see excessive black exhaust. This is an indication that you have a rich fuel mixture in the engine. This can be caused by a faulty turbocharger, a broken EGR valve, or leaking fuel injectors.
Excess Noise
Finally, your diesel engine will always be louder than a gasoline engine, but it should be excessively loud. If it is, you may have an exhaust system problem. You may also hear loud knocking noises if the diesel engine is having problems firing up the air and fuel.
