6 Issues That Call for Diesel Engine Repair Service

Diesel engine repair for Mercedes Diesel engines are popular in pickup trucks and certain passenger cars because they are more fuel-efficient than gas engines. People who use their trucks for work prefer diesel engines for that and because they have more low-end torque than gas engines. Diesel engines also last longer than gas engines in most cases. That being said, they do have their problems. Just like with gas engines, parts wear out.

Issues that Require Diesel Engine Repair Service

When you bring your vehicle in for diesel engine repair service at RDI Power in Brooksville, you receive a 2-year, 24,000-mile warranty on fleet vehicles and a 3-year, 36,000-mile labor warranty on other vehicles. We also offer discounts for military personnel, firemen, and police officers.

Issues you should be on the lookout for include:

1. Oil Oxidation

When too much air gets into the oil, such as when you leave your truck sitting for a long time, the oil could oxidize. The air bubbles in the oil destroy the oil’s lubrication properties, which then causes damage to the engine. Always change the oil after letting a diesel truck sit for a long time unless you regularly start the truck.

2. Power Loss

If you don’t properly maintain a diesel truck, including changing the filters, cleaning the fuel injectors, checking and tightening the throttle linkage as needed, or if the truck has excessive lubrication, it could lose power. RDI Power in Brooksville, FL, can diagnose loss of power issues, make the repairs and get you back on the road again.

3. Black Exhaust

If you see black exhaust, you have an issue with the air and fuel mixture in the engine. It means that the mixture is too rich – it has too much fuel. Bad ignition parts, fuel components, and sensors could cause the engine to run rich. Black exhaust could be an emergency since a rich engine could cause additional interior engine damage. Always have an experienced diesel mechanic diagnose the reason for black smoke – some of the reasons are difficult to locate.

4. Glow Plug Failure

Many diesel engines use glow plugs to heat the cylinders. Diesel is not as explosive as gas, so the heat in the cylinder needs to be higher to ignite the air and fuel mixture easier. If a glow plug is not working, the engine might not start. It might also expel a grayish-white smoke with a different smell out of the exhaust.

5. Noisy Engine

Some diesel engines are loud, especially the older engines. New technology makes them almost as quiet as a gas engine. However, regardless of the age of your diesel engine, if it makes too much noise, that is a sign that you need diesel engine repair service. Knocking noises could mean a spun bearing, bent rod or other internal engine issues. Your vehicle’s fuel injectors can also cause a compression knock if they are going bad. Rattling, or pinging, means the air and fuel mixture ignites too early, usually in the compression stroke. And, timing chains that are too loose will also cause knocking sounds.

6. Contaminated Fuel

Because diesel fuel’s viscosity is higher than gasoline, it is that much easier for it to become contaminated. It could become diluted, full of soot, or mixed with water or glycol. When you catch contaminates sooner rather than later, you could save on an expensive repair. If you don’t catch the contamination, you’ll have to purge the engine’s fuel tank. If you suspect any contamination, it is better to be safe and have an experienced diesel technician at RDI Power check the fuel system.
