Ford 6.0 Injectors

The Ford 6.0 injectors are known to be problematic and can be very expensive to replace. Most of the failures have been related to the oil side of the injector that uses crankcase oil pressurized to approx. 3000 psi to fire the injector. With using crankcase oil in the small passages in the injectors you can restrict the passages with oil varnish, oil deposits and soot in suspension in the oil. As the deposits build up in the oil passages the volume and pressures will be effected resulting in the injector firing compromised. The easiest way to see this is to check cylinder balancing rate, you'll be able to see the adjustments to firing made to keep everything even. Utilizing BG's 109 product prior to an oil service will clean those oil passages to great effect slowly dissolving and dispersing the varnishes and deposits. You will see the improvement to cylinder balancing rates in a very impressive manor in scan tool data with an improvement to driveability. Post oil change utilizing a very high quality full synthetic oil like BG's 716 Shear Power and the DOC oil conditioner will reduce the rate at which the oil deposits can form and attach to surfaces in a oil passage.
