Tamerx Diesel Products 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 Tamerx Diesel Products 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.

Tamerx Diesel Products 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 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 valve cover gasket injector harness for International Navistar MaxxForce DT, 9, and 10 engines plays a critical role in ensuring that the engine operates efficiently. The OEM 1850500C91 component is designed to seal the valve cover, protecting the internal parts from contamination while allowing the injector harness to function properly.

This gasket works in two important ways:

  • Seals the Valve Cover
    • It prevents oil leaks and keeps debris from entering the engine, which could cause significant damage over time.
  • Supports the Injector Harness
    • The injector harness, which is housed within the valve cover, sends electrical signals to the fuel injectors, ensuring that the correct amount of fuel is delivered to the engine.

Signs that the valve cover gasket or injector harness may need attention include:

  • Oil leaks around the valve cover area
  • Electrical malfunctions with the injectors
  • Misfiring or reduced engine function

Replacing this gasket promptly when these symptoms appear can prevent more costly engine issues down the road. By keeping your engine sealed and running smoothly, this component helps extend the overall life of the engine.

The valve cover gasket injector harness plays a crucial role in keeping your engine running smoothly. Over time, wear and tear can take a toll on this component, leading to potential issues in your engine. Knowing when to replace it can save you from costly repairs.

Here are some key signs that it’s time to replace your valve cover gasket injector harness:

  • Oil leaks
    • around the valve cover area.
  • Engine misfires
    • due to poor electrical connections.
  • Loss of power
    • when driving, particularly during acceleration.
  • Check engine light
    • coming on frequently.

If you notice any of these issues, it may be time to inspect your valve cover gasket injector harness and replace it if necessary. Ignoring the signs can lead to further damage, potentially affecting other engine components.

Regular inspections and timely replacements of the valve cover gasket injector harness can prevent engine troubles and ensure your vehicle runs efficiently. If you need high-quality replacement parts, consider reaching out to trusted suppliers that offer durable and reliable options for your specific engine model.

Check for oil seepage, inspect injector codes with a scan tool, and test harness continuity for voltage drops or shorts.

Yes, oil intrusion into the electrical connectors can interrupt current flow and cause injector signal loss.

Continued leakage may lead to engine contamination, poor injector operation, misfires, or wiring damage.

Yes, it operates in a high-heat zone, making it prone to heat-induced wear and hardening over time.
