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.

As is the case for the majority of the diesel products sold on Tamerx Diesel Products, 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). Tamerx Diesel Products 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 Tamerx Diesel Products, 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. Tamerx Diesel Products 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 Tamerx Diesel Products 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 6395667) operates under constant heat, pressure, and high rotational speeds, making routine care essential for long-term reliability. While the turbo itself requires little direct maintenance, the systems that support it have a major impact on how long it lasts.
A well-maintained turbo can provide years of dependable service, while neglected maintenance elsewhere in the engine can shorten its lifespan significantly.
Here are some practical ways to help protect your turbo assembly:
- Make oil changes a priority
- The turbo depends on clean engine oil for lubrication and cooling. Fresh oil helps protect internal bearings and moving components from excessive wear.
- Keep the air filter clean
- Dirt and debris entering through a clogged or damaged air filter can damage the turbo's compressor wheel and reduce its efficiency.
- Inspect hoses and clamps regularly
- Loose connections, cracked hoses, or air leaks can disrupt airflow and force the turbo to work harder than necessary.
- Allow the engine to warm up before heavy use
- Giving oil time to circulate properly helps protect the turbo during startup.
- Let the engine idle briefly before shutdown
- After towing, hauling, or extended operation, a short cooldown period helps reduce heat stress inside the turbocharger.
- Watch for unusual signs
- Whistling noises, increased exhaust smoke, oil leaks, or sluggish engine response may indicate developing turbo issues that should be inspected promptly.
- Maintain the fuel and emissions systems
- Proper combustion and healthy aftertreatment components help create stable exhaust conditions, which are important for turbo operation.
- Perform routine visual inspections
- Check for oil residue, damaged connections, or signs of wear around the turbo and surrounding components.
Think of the Cummins 6395667 turbo as a component that thrives on clean oil, clean air, and proper operating habits. By staying proactive with maintenance and addressing small issues early, you can help maximize the lifespan of your turbo assembly and keep your engine operating reliably.
While your vehicle may still run with a bad turbo assembly, continuing to drive for an extended period is generally not recommended. A failing turbo can affect engine operation, fuel efficiency, and, in some cases, lead to more serious mechanical problems if left unaddressed.
The severity of the issue depends on the condition of the turbocharger and the type of failure involved. What starts as a minor loss of efficiency can eventually develop into a costly repair.
Here are some risks of continuing to drive with a bad turbo assembly:
- Reduced engine performance
- A failing turbo may not provide the airflow needed for proper combustion, causing sluggish acceleration and reduced responsiveness.
- Increased fuel consumption
- The engine may use more fuel to compensate for reduced airflow and inefficient combustion.
- Excessive exhaust smoke
- Worn seals or internal damage can allow oil to enter the exhaust system, producing blue, black, or white smoke.
- Higher risk of engine damage
- If the turbo experiences a catastrophic failure, metal fragments or excessive oil can enter the intake system and damage internal engine components.
- Oil leaks and lubrication issues
- A damaged turbo can consume or leak oil, potentially leading to low oil levels and accelerated engine wear.
- Unexpected breakdowns
- Ignoring turbo problems can increase the likelihood of a complete failure, potentially leaving the vehicle stranded.
If the symptoms are minor, driving a short distance to a repair facility is usually acceptable. However, if you're experiencing significant power loss, excessive smoke, unusual noises, or heavy oil consumption, it's best to stop driving and have the turbo inspected as soon as possible. Early repairs can help prevent more extensive damage and reduce overall repair costs.
Yes. Excessive vibration from engine, exhaust, or mounting issues can place additional stress on turbocharger components and reduce their lifespan.
The turbocharger is built with heat-resistant materials and engineered clearances that accommodate thermal expansion during normal engine operation.
The exhaust manifold directs exhaust gases toward the turbine housing, providing the energy needed to drive the turbocharger.
The turbocharger is calibrated to match the airflow requirements, exhaust characteristics, electronic controls, and emissions systems used on Cummins B6.7 engines, ensuring proper system integration and performance.
