LB7 Injector Sleeves
I'm playing Diesel Mechanic and I just removed the 4 injectors on the passenger side because I was told that I have coolant leaking into my #7 cylinder (hopefully not a head gasket leak). So I pulled #7 injector to reseal the sleeve and then decided to pull the other 3 injectors to see how they looked. Does pulling the injectors compromise the seal under the sleeve? Should I pull all the sleeves and reseal? Truck was running fine except for white smoke. 122K miles, out of 7 yr warranty, injectors changed twice. Should I take injectors in to be cleaned and bench tested?
