Excessive carbon deposits around all injectors and injector wiring due to failure of injector copper washer seals. The fault is caused by contaminated injectors causing an excessive increase in combustion pressure.
The fault was cured by using Forté Air Intake Cleaner to soak into and soften the carbon deposits to remove the injectors and wiring, replacing the injector copper washer seals and adding Forté Advanced Formula Diesel Treatment to the fuel tank to clean the fuel system and restore the injector spray patterns.
Forté's Technical Helpline receives over 300 calls per month. This blog shares solutions for garage workshops on common driveability concerns that can be quickly and effectively treated. The vast majority of those identified are caused by fuel and oil borne contamination formed by natural degradation or via the combustion process. This is a fact of life for internal combustion engines where fossil fuels and oils are used.
