# Service bulletin CPI375841

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

Fuel is leaking past the injector tip seal, into engine oil resulting in oil dilution with fuel. A newly designed double delta check seal and backing plate are undergoing field validation and bench tests at this time. Testing for both the field and lab will continue until test thresholds are met.
