Hi, new to the site and looking for ideas/suggestions for my 2006 F-250 6.0 FX4. My truck has 349,000 miles with #3 cylinder dead due to the lifters. The only repairs needed on it has been the high pressure oil pump, EGR valve, and the Fuel module control unit. No other issues until now with the #3 cylinder lifters. I really do not want to by a new truck right now so I'm thinking about an engine/transmission rebuild. Would this be throwing money away or something to conciser.
