The 6.0 Powerstroke left a sour taste in the mouths of many Ford Truck Owners. An inadequate EGR System and poor Injection components made for headaches for thousands of owners. International/Fords 6.4L was a mile ahead of its predecessor and a completely new design, using modern Common Rail Injection and Emissions Control as well as a Compound Turbocharger. The 6.4 much like its predecessor is still not without problems, often stemming from Poorly designed Emissions Control Systems. A customer came in with the symptoms of a Blown head Gasket, as well as a possible failure of the EGR System. The customer elected to have the heads removed & checked, as well as the installation of ARP Headstuds, Coolant Filter, EGR check-up as well as a new high flow intake elbow and intercooler boot kit. The end result was the improvement of an already great motor, we addressed the shortcomings International Faced when working around the 2008 emissions standards.
