Actually, my MH is an E-450 on a 1999 chassis (2000 MH). As for what years the problem exists, I'm not sure, but I think it was '99 thru '04. The problem was described by Ford as the fault of incorrect plug torque or improperly cleaning when changing plugs. They have never admitted to there being too few threads although the problem seems to have miraculously gone away after the heads were modified - for the 3 valve engine, I think. Still, no known history of blowing tires. Perhaps it could have been a specific make/model that was near overload on one side at the rear???Gary RV Roamer said:Are we talking about tire blowouts or something else? Any particular year - the E450 cutaway chassis has been available since about 2001 and has come in several different configurations.
In broad terms, I haven't heard of any general complaints about the E450 chassis, but the early V10 engines did have the spark plug issue that Molaker mentioned. That was not unique to the E450, though.
So, I did Google it and yes there were problems, but it seems to be as much a Firestone problem as a Ford problem. The Ford SUVs had a problem then, too, and they were Firestones. Firestone never admitted a problem, but Ford dumped them and the problem seems to have gone away.floyd2u said:If you Google E-450 right rear tire blow out you will find A lot of info on it. Looks like mainly in hot climates.
Now would this spark plug blow out problem stop you from buying a 2001 rig with the V-10???
