ya.. the 03.5 -06 were crap... call me crazy but as a wrecker operator I seemed to tow that trash every other day.. lets see... injectors, head gaskets, head bolts, blown turbo's, etc.. and the 6.4's weren't a ton better.. here's a fact jack.. Change the OIL 3000 MILES, not 3001, not 10,000 miles. 3000. It builds up like these sulfur like balls that choke the ever living daylight out of the motor, and that's what usually leads to the things blowing up, and has earned the name of POWERCHOKE... now a v 10 is almost indestructable minus some coil pack issues.. but PM is a big thing.. and some people get it, and a ton more don't.. as for the 5.4 triton.. they tend to shoot plugs out of the block.. i dunno.. I still drive ford.. I got a 96 exploder pusing 200K with no hesitation.. better than a leaky, drippy, chebby. IMHO..
