Critical Purpose in Injector Sleeve Installation:

During the installation of any new injector sleeve, the integrity of the O-ring seal is paramount. It is an absolute necessity to remove the old O-ring from the sleeve bore and replace it with a new one of the correct specification. For proper seating and to ensure a reliable, leak-proof fit, the new O-ring must be adequately lubricated with clean engine oil prior to installation. This step prevents damage to the O-ring during seating and ensures it forms a perfect seal against combustion gases and coolant.

Consumable Item & Quality Assurance:

These O-Rings are essential consumable items, meaning they are designed for single use and must be replaced each time an injector sleeve is serviced. While crucial, they are often listed as supplementary items that may be needed separately and are not always part of the standard complete installation kits for the 250 Series.
