SHIPPING POLICY

Drive On Diesel ships via UPS Ground. Next day air shipping can be arranged for a reasonable price of anywhere from $50.00 - $100.00 depending on the weight of the product and your location. We will do everything we can to make sure that you get the service you need. We understand how important it is to receive your order as quickly as possible.
In most cases Drive On Diesel only needs one address, as long as your product is shipping to the same location as your billing information. In order to eliminate credit card fraud, your billing information must match the credit card you provide.

The terms, conditions, and details of our warranty vary from product to product. Specific warranty details can be found below.

Drive On Diesel provides a replacement warranty on all of our parts. The duration and mileage limitations of the warranty vary by product and are specified on the product's detail page/item listing.

Please note that the warranty covers replacement of the part and the cost of shipping the replacement part to you only. It does not cover any shop, labor, towing, or any similar or related costs. This is not a "money back guarantee".

If you experience a problem with your part or it is not functioning properly, the correct warranty procedure is to call us at (510) 257-1777 (8:00 AM - 5:00 PM ET Monday through Friday). Be sure to have your order number and/or other relevant order information ready so we can easily locate your order and resolve your issue as quickly as possible. From that point, we will review with you any troubleshooting steps that may need to be taken and other areas or systems that can be checked to rule out external problems contributing to your part's issue. If a replacement is determined to be necessary, we will then arrange for your replacement part to ship out ASAP and issue any necessary return shipping labels and/or documents.

As is the case for the majority of the diesel products sold on Drive On Diesel, your part's warranty is active as soon as you install it. In some other cases, warranty activation is contingent upon you sending us your core (i.e., your old part). Drive On Diesel will provide you a return shipping label for parts that have a warranty with a core return condition. When we have received your core return, the part's warranty coverage begins. We reserve the right to void the product warranty if your core is not received within the allotted time, or if it isn't received at all. If the warranty for the diesel part you are purchasing has a core return requirement, it will be clearly noted on the product detail page/item listing.

What is a Core Charge?

A core charge (also called "core deposit") is similar to the deposit you might pay for a can or bottle of soda and is a standard requirement in the auto parts industry. For example, in many states, to promote recycling, you pay a deposit when you purchase a can of soda and receive your deposit back when you return the empty can. Many automotive parts have a core charge, or core price, that works in essentially the same way as a soda can deposit.

30 Day Core Charge Hold

You authorize Drive On Diesel, to hold your credit card for the specified core charge amount and that you agree to return your core with 30 days of receiving the purchased part. When we have received your core return, the hold is released and the core charge payment is canceled.

The customer, or parts buyer, is responsible for any shipping costs associated with core returns unless otherwise specified in the product listing/detail page. Drive On Diesel offers prepaid UPS shipping labels (SKU numbers UPS-CR1 and UPS-CR2) for use in returning your core that are available for purchase on our website during your shopping/order process.

The shipping label you will need to use for the core return is dependent upon what part you are purchasing. UPS-CR1 is good for cores weighing up to 20 pounds. UPS-CR2 is appropriate for shipping cores weighing 21 pounds or more. You must include enough information with the core return that clearly identifies it as a.) a Core Return, and b.) contains enough information we can use to clearly associate the core return with your order. Including a copy of the invoice or packing slip that came with the original shipment, clearly marked "Core Return", is ideal. Alternately, you can include a note marked as "Core Return" that includes your order number, full name and address, and phone number or other contact information. Failure to include this information with your returned core will most likely delay any due core credit being issued and/or delay any applicable warranty activation. Core returns need to be for the exact part purchased and cannot be damaged. Substituting another part in place of the part you have purchased is not acceptable.

All fluids must be drained.

If you have purchased a set or a parts package, you will need to return cores for all components of the set. For example, if you have purchaed a high pressure oil pump with an IPR valve, you will need to return both HPOP and IPR valve cores to receive proper credit. If you have purchased an EGR cooler/EGR valve package, your core return must consist of an EGR cooler core and an EGR valve core, or core credit will not be given.

Core Charges are often mandated by state legislature, and, as such, the actual core charge and taxes on the charge may vary depending on the state in which you buy your part. The Drive On Diesel core charge presented to you online today with your item is representative of the most common core charge.

A properly functioning turbo assembly is essential for optimal combustion and efficiency in diesel engines. The JCB 3.9L Turbo Assembly (OEM 2674A160) is built to deliver the airflow your engine needs to maintain reliable performance. When this component begins to fail, early warning signs can prevent costly repairs and unplanned downtime.

Symptoms of Turbo Failure in a JCB 3.9L Engine:

  • Reduced Engine Power – A worn or damaged turbo can’t supply sufficient airflow, limiting acceleration and responsiveness.

  • Unusual Noises – Whistling, whining, or grinding sounds may indicate internal bearing failure or contact damage.

  • Oil Around the Turbo – Leaks near the housing or connections suggest seal deterioration.

  • Increased Exhaust Smoke – Excessive black or blue smoke often points to oil leaks or fuel-air imbalance.

  • Poor Fuel Efficiency – A faulty turbo can lead to inefficient combustion and increased fuel consumption.

Why Choose the OEM 2674A160 Turbo Assembly:

  • Specifically engineered for JCB 3.9L engine systems

  • Ensures proper airflow and combustion balance

  • Built to original equipment standards for durability and fit

  • Supports emissions compliance and stable engine operation

  • Direct replacement for quick installation and minimal downtime

Recognizing the early signs of turbo failure can save time, money, and frustration. If your JCB 3.9L engine is showing signs of a failing turbo, the OEM 2674A160 Turbo Assembly is a reliable replacement option. Trust TamerX Diesel Parts for high-quality, OEM-compatible components designed to keep your equipment running with confidence.

The turbo assembly is a vital part of many diesel and gasoline engines, designed to boost air intake for better combustion efficiency. While turbos are engineered to handle high pressure and heat, they don’t last forever. Understanding how long a turbo assembly typically lasts—and what factors influence its lifespan—can help you plan for maintenance or replacement before problems arise.

Average Turbo Lifespan and What Affects It:

  • Typical Lifespan – Most turbo assemblies last between 100,000 and 150,000 miles, though many can exceed this with proper care.

  • Maintenance Habits – Regular oil changes and clean air filters help reduce wear and prevent premature failure.

  • Driving Conditions – Frequent towing, high-speed driving, or aggressive acceleration can shorten turbo life due to increased stress.

  • Engine Oil Quality – Clean, high-quality oil is essential for lubricating the turbo’s moving parts and managing heat.

  • Cool-Down Practices – Allowing the engine to idle briefly before shutdown can prevent heat soak and extend the turbo’s lifespan.

  • Air and Oil Contamination – Debris entering through the intake or oil system can damage turbo bearings or blades.

  • Manufacturer and Design – Some turbos are built for heavy-duty use and may last longer depending on build quality and application.

A turbo assembly is built to last for many miles, but its actual lifespan depends on how well the vehicle is maintained and how it's driven. By following proper maintenance routines and being mindful of driving habits, you can help ensure your turbo continues to operate efficiently and reliably for years to come.

Frequent oil changes with clean, high-quality oil help lubricate and cool the turbo bearings effectively.
