The Benefits of Engine Rebuilds

If your semi-truck's engine is experiencing significant wear and tear or has broken down, you may be wondering whether to replace or rebuild the engine. While replacing the engine may seem like a more convenient option, rebuilding the engine can offer a range of benefits. Engine rebuilds are generally more cost-effective than engine replacements and can extend the lifespan of the engine by replacing damaged parts with new ones, ultimately reducing the risk of future breakdowns. Additionally, rebuilding an engine can help to improve its overall performance and fuel efficiency, making it a worthwhile investment for your truck.

Common Diesel Engine Issues

Diesel engines are known for their durability, but they still experience common issues that need attention. These issues include problems with the fuel system, such as a clogged fuel filter or fuel injectors, problems with the exhaust system, such as a faulty turbocharger or EGR system, and issues with the engine's electrical system, such as a failing starter or alternator. Our team of diesel engine repair specialists has the knowledge and expertise to diagnose and repair these issues, getting your truck back on the road in no time.

What Our Customers
Are Saying About Us

We had a truck lose power at a receiver, and called them for assistance with a jump start. The mechanic was there in less than an hour and got our truck started and back on the road. Quick and efficient, would use them again.

Had excellent experiences with Dave and Jan at QMFS San Diego.  These folks care about their customers and back up their promises with solid mechanics that got one of my drivers back on the road and we have used them ever since when in the San Diego area weekly.

Jan and her lead mechanic were excellent.  They got our Volvo in the shop promptly and got it diagnosed and repair faster and less expensive than the other shops we were quoted.  I fully recommend their commitment to helping companies and people that are in need . Eric Z
