Welp my radiator is slam full of fuel. There is known issues with isx injector cups. That said there are two TSB out one for SOHC and one for DOHC. I have a cm870 with the DOHC. They have an updated lower injector O ring for this one. Does anybody have experience with this repair? Truck just needs to last another 4 or 5 months. @pushbroom ? Anybody?
