The 6. 8 and 5. 4 engines have been failing due to defective valve train cam followers. I am having the 3rd engine installed in my Excursion. The cam followers are failing and spitting them out causing catstropic engine failure. I have been in contact with anthony bariana who works for holman distribution in new jersey @ 1-800-521-1223 ext 305 and he confirmed that the 6. 8 and 5. 4 engines have had the same problem as my truck at an abnormally high rate. Mt truck is currently at matthews paoli Ford 610-644-4700 and the general manager bryan lippincott told me that they have replaced 6 state farm truck engines in 2. 00 months 6. 8 liter same as mine identical problem. Ford has done nothing from what I see doing some research but this is an ongoing problem and Ford has done nothing to address the problem and made no attempt to find the root cause and have a fix so this will stop costing consumers thousands of dollars. I was driving on my street and without warning the engine started to shake so I shut it off and had it towed to the dealer matthews Ford located in paoli PA.
