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.

The Cummins B6.7 Turbo Assembly (OEM 6395665) is built to operate in one of the toughest environments on the engine, handling extreme temperatures, constant airflow changes, and high-speed rotation. Because of this, proper care is essential if you want to maximize its lifespan and avoid unexpected repairs.
The good news is that turbo maintenance is largely preventative. By taking care of the systems that support the turbo, you can help keep it operating reliably for years to come.
Here are some of the best ways to care for your turbo assembly:
- Keep your engine oil clean and fresh
- The turbo relies on a continuous supply of clean oil for lubrication and cooling. Delayed oil changes can lead to increased wear on internal turbo components.
- Replace air filters as recommended
- A clean air filter helps prevent dirt and debris from entering the turbocharger, protecting the compressor wheel from damage.
- Inspect intake and charge air piping
- Cracked hoses, loose clamps, or leaks can disrupt airflow and place unnecessary stress on the turbo system.
- Allow for proper warm-up time
- Giving the engine a few minutes to circulate oil before demanding operation helps protect the turbo from premature wear.
- Avoid immediate engine shutdowns after heavy use
- Letting the engine idle briefly after towing, hauling, or extended operation helps dissipate heat and reduce thermal stress.
- Watch for early warning signs
- Unusual noises, excessive exhaust smoke, oil residue near the turbo, or reduced responsiveness may indicate a developing issue that should be inspected promptly.
- Maintain the fuel and emissions systems
- Poor combustion can affect exhaust conditions, which directly impacts how the turbo operates.
- Perform routine visual inspections
- Periodically check for loose hardware, damaged connections, or signs of leaks around the turbo assembly.
In simple terms, the best way to extend the life of your Cummins 6395665 Turbo Assembly is to focus on clean oil, unrestricted airflow, proper operating habits, and early detection of potential issues. A little preventative care can go a long way toward keeping your turbo working efficiently and reliably.
A turbo assembly rarely fails without warning. In most cases, it will show several symptoms before a complete breakdown occurs. Recognizing these signs early can help prevent more expensive repairs and reduce the risk of damage to other engine components.
Because the turbo is responsible for supplying compressed air to the engine, any decline in its condition can quickly affect overall drivability.
Here are the most common signs of a failing turbo assembly:
- Loss of acceleration and engine response
- If the turbo is no longer producing the proper amount of airflow, the vehicle may feel sluggish and less responsive, especially when accelerating or carrying heavy loads.
- Excessive exhaust smoke
- Blue smoke may indicate oil leaking past turbo seals, while black smoke can signal an imbalance in the air-fuel mixture caused by inadequate airflow.
- Whining, grinding, or rattling noises
- Unusual sounds coming from the turbo area often point to worn bearings, damaged turbine blades, or internal component wear.
- Increased oil consumption
- A failing turbo can allow oil to leak into the intake or exhaust system, causing oil levels to drop faster than normal.
- Check engine light or boost-related fault codes
- Modern engines monitor turbo operation and may trigger warning lights when abnormal boost levels are detected.
- Visible oil leaks around the turbocharger
- Oil accumulation near the turbo housing or connected piping can indicate failing seals or internal wear.
- Inconsistent boost pressure
- Fluctuating boost levels can cause uneven engine operation and are often a sign of turbocharger problems.
Addressing these warning signs early can help prevent complete turbo failure and protect your engine from additional damage. If you notice multiple symptoms at the same time, it's a good idea to have the turbo assembly inspected as soon as possible.
The compressor wheel draws in filtered air and compresses it before sending it through the charge air system and into the engine intake.
