Re: C7 Injector Crack

Did anyone socalled "serviced" these injectors??

the bottomside seems quite hammered, cant say from this image if this is rootcause or followed.

 

just wordering how high is your fuel temperature??

i seen before injectors cracking this was caused by a too high fuel temperature.

the high temperature caused the needle to cease in the tip, due to the pressure buildup during the injection the injector tip split in 2 pieces.
