Thanks for fixing my 2007 Chevy Diesel Silverado Crew Cab Dually. I knew I could depend on you. She’s running great! I can’t wait to take out the trailer and kids and go camping in the woods. It’s really nice to have my truck back and running better than new!

FAQs About Diesel Repair

How Many Miles To Service Diesel Oil?
It is important to follow the vehicle manufacturer’s recommendations for oil changes and diesel service. For most vehicles, this is at 7500 miles, but with city driving, towing, or long periods of idling, the service may be required at closer to 5000 miles.
What Causes Diesel Engine Failure?
The most common causes of diesel engine failure are water in the fuel and failure to correctly maintain the diesel engine. Poor quality coolant and failing seals can allow small debris and contaminants in the system that contribute to poor performance and diesel engine failure.
How Often Should A Diesel Engine Be Serviced?
Most manufacturers recommend diesel engines are serviced every six months or every 5,000 – 7,500 miles. Depending on the amount you drive, it may be more appropriate to choose the mileage over the number of months.
Why Is My Diesel Engine Producing Smoke?
Diesel engines can produce black, gray, or white smoke when there is a problem. Black smoke indicates the diesel is not fully combusting the fuel, which can be caused by problems with the injectors, valves, or timing issues. It is also commonly seen with poor quality diesel fuel, dirty air cleaners, or problems with carbon buildup in the exhaust and combustion systems.

Blue or gray smoke is an indicator of burning oil. Oil is entering the combustion chamber through worn seals or valve guides, problems with the turbocharger seal, or problems with the grade of oil used with the last oil change.

White smoke is due to the presence of diesel in the exhaust. This is unburned diesel, which is typically a sign of fouled piston rings, problems with injection timing, damaged or worn injectors, or low compression in the cylinder.

How Often Should Diesel Injectors Be Serviced?
Always check the manufacturer’s recommendations for diesel injection service schedules. The recommendation for most newer vehicles is at least once a year or every 30,000 plus miles. The ideal solution is to keep the injectors clean to prevent any drop in performance and fuel economy, while also helping to extend the life of the engine. For heavy use vehicles, more frequent cleanings may be recommended.
