How Air in the Fuel System Can Cost Thousands of Dollars in Repairs
Another area of concern we have on the 6.0L Powerstroke/VT365 injectors is the separation of the stator housing from the injector body. The stator is the electronically-controlled assembly on the top of the injector which contains the high-pressure oil inlet, the spool valve, and the control coils. This type of failure is generally attributed the injector over-pressurizing with engine oil, which overcomes the strength of the two bolts holding the stator housing to the body of the injector and popping it off. This failure will be immediately apparent to the driver, as the engine will have an immediate ‘dead miss’ on the affected cylinder.
The best ways to prevent these failures from happening to your engine is to perform routine maintenance:
- Changing your fuel filters (primary & secondary) at least every other oil change.
- Use good quality fuel from a reputable supplier, ideally from a station that has high-volume sales.
- Address any suspected fuel system problems promptly, before more severe damage has a chance to occur.
