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.

The JCB 4.4L Turbo Assembly OEM 802455-5002S is designed to restore engine balance and prevent long-term damage caused by airflow disruption.

Common Indicators of a Failing Turbo in JCB 4.4L Engines:

  • Loss of Power – Sluggish acceleration or reduced torque may signal a drop in boost pressure.

  • Whining or Whistling Sounds – Unusual noises often point to damaged internal bearings or seals.

  • Excessive Exhaust Smoke – Blue or black smoke may indicate oil entering the combustion chamber.

  • Oil Leaks Around Turbo Housing – Deteriorating seals can lead to visible leaks near the turbo assembly.

  • Decreased Fuel Efficiency – A malfunctioning turbo can lead to incomplete combustion and increased fuel use.

A turbo assembly is a high-performance component designed to boost engine efficiency and power. However, due to the high temperatures and pressures it endures, it requires proper maintenance to stay in top shape. With consistent care, you can extend the life of your turbo and avoid premature failures or costly repairs.

Tips for Maintaining Turbo Reliability Over Time:

  • Change Engine Oil Regularly – Clean, high-quality oil keeps the turbo’s bearings and components well-lubricated and free from harmful deposits.

  • Use the Correct Oil Type – Always use the manufacturer-recommended oil to ensure proper flow and protection under high heat.

  • Let the Engine Idle After Hard Driving – Allowing the engine to idle for 1–2 minutes helps cool the turbo and prevents oil from burning inside the unit.

  • Replace Air Filters on Schedule – Clean air filters prevent debris from entering the turbo and damaging the compressor wheel.

  • Check for Leaks – Regularly inspect oil and boost lines for signs of leaks that could lead to pressure loss or turbo damage.

  • Avoid Abrupt Engine Shutdowns – Turning the engine off immediately after high-speed driving can cause heat soak, damaging internal components.

  • Monitor for Warning Signs – Whining noises, black smoke, or reduced power could indicate early turbo issues—don’t ignore them.

  • Use Quality Parts and Fluids – Cheap or incompatible fluids and filters can compromise the turbo’s performance and longevity.

Maintaining your turbo assembly isn’t difficult—it just requires consistency. By sticking to a regular service schedule, using quality fluids, and being mindful of how you drive, you can ensure your turbo remains reliable and efficient for the long haul. Proactive care always pays off in performance and peace of mind.

Common signs include loss of power, whining noise, black smoke, and excessive oil consumption.
