The 12-valve Cummins engine holds a legendary status among diesel enthusiasts. Known for its robust build, impressive torque, and relative simplicity, it's a favorite for everything from heavy-duty trucks to custom projects. But finding a readily available, remanufactured "crate" motor can be tricky. This comprehensive guide explores the world of 12-valve Cummins crate engines, addressing common questions and concerns.
What is a 12-Valve Cummins Crate Engine?
A "crate engine" is a completely assembled engine, ready to be installed. It's shipped in a crate, hence the name. In the case of a 12-valve Cummins crate motor, you're getting a fully rebuilt or remanufactured engine, typically featuring updated components and rigorous testing to ensure quality and reliability. This eliminates the need for individual parts sourcing, rebuilding, and assembly, saving you considerable time and effort. However, finding a genuine "crate" version specifically labeled as such can be challenging, as many are sold as remanufactured or rebuilt units.
Where Can I Find a 12-Valve Cummins Crate Motor?
Locating a 12-valve Cummins crate engine requires some searching. While Cummins itself doesn't typically offer crate engines in the same way some automotive manufacturers do, numerous reputable engine rebuilding shops and parts suppliers specialize in Cummins engines. Your best bet is to contact these specialists directly, explaining your needs and specifications (engine model, horsepower requirements, etc.). Online marketplaces and forums dedicated to diesel engines can also be valuable resources. Be sure to carefully vet any supplier before committing to a purchase.
What are the Benefits of a Remanufactured 12-Valve Cummins?
Choosing a remanufactured 12-valve Cummins, whether sold as a "crate" engine or not, offers several advantages:
- Reliability: Remanufacturing processes typically involve replacing worn-out components and performing rigorous testing, ensuring a much longer lifespan than simply rebuilding a used engine.
- Warranty: Reputable suppliers usually offer warranties on their remanufactured engines, providing peace of mind.
- Convenience: You receive a ready-to-install engine, eliminating the time and expertise needed for sourcing parts and assembling the engine yourself.
- Performance: Often, remanufactured engines are enhanced with updated components, potentially increasing performance and efficiency.
How Much Does a 12-Valve Cummins Crate Engine Cost?
The price of a 12-valve Cummins remanufactured engine varies greatly depending on factors such as the engine's condition, specifications (horsepower, torque), and the supplier. Expect to pay a significant amount—thousands of dollars—for a high-quality, remanufactured engine. Always obtain multiple quotes before making a purchase.
What are the Different Models of 12-Valve Cummins Engines?
The 12-valve Cummins engine family encompasses several models, each with varying specifications. These models differ in displacement (engine size), horsepower, and torque output. Knowing the specific model you need is crucial when searching for a remanufactured engine.
What are Common Problems with 12-Valve Cummins Engines?
While known for their reliability, even 12-valve Cummins engines can experience issues. Common problems include injector pump issues, cracked cylinder heads (especially in higher-performance applications), and potential wear on components like lifters and pushrods. A reputable remanufacturer should address these potential issues during the rebuilding process.
Can I Use a 12-Valve Cummins Crate Engine in My Vehicle?
The suitability of a 12-valve Cummins crate engine for your vehicle depends on various factors, including the vehicle's chassis, existing engine bay space, and necessary modifications (potentially involving wiring, cooling systems, and mounting). Careful planning and potentially professional guidance are necessary to ensure compatibility.
This guide offers a comprehensive overview of 12-valve Cummins crate motors. Remember to carefully research and compare options before committing to a purchase, ensuring the supplier is reputable and the engine meets your specific needs and expectations. The legendary reputation of the 12-valve engine ensures that investing in a properly remanufactured unit can yield many years of reliable power.
