F 450 Super Duty gasser

Blown out plugs? What are the cylinders suddenly developing 5000 psi per cyl? There was a rash of bad castings around the plug holes to relieve the much greater pressures the valves see? I can't believe some of the crap I see posted here.

It's a real problem.

In my opinion it's the biggest problem with that generation of ford pickups.
The dealers were looking people straight in the eye and recommending replacing the head. And to do this, they pulled the cab.

If there ever should have been a recall or at least a reduced price repair, this is it.

I own a 2001 5.4l. Blew one plug, 500 miles from home, no tools. Long story.......

The quoted article does not mention the v-10 6.8l engines. I smell some anti ford bias here. In fact I can't find a single instance of a "blown plug" in the 6.8l V-10 engine on the whole internet.

I might point out that the OP asked about this engine specifically, I don't think the colloquial experience about 5 or 10 of the millions ford trucks on the road is a comparative example.

Ford biased? You're kidding? Everyone here is giving it a green light for the most part and just pointing out the (minor) flaws that do exist in this series of engines. If your "experience" only goes as far as the internet searching, this is where the conversation would leave you. It does happen on the 6.8, much less common however.

You don't have to pull the cab. On the diesels it makes life easier and shortens some jobs but the gassers don't require it.

We had 3# 7.3Ls in the family business. (94 no turbo, 02, 99). All 3 trucks pulled a 10,000 trailer fairly often and plowed for the state. They were good engines, I still am fond of them. However, starters, alternators, turbos, oil pans, oil coolers, injection pumps, we had to replace them more than once. Not to mention oil changes cost a lot more with a bigger filter and twice the oil. Along with cold issues. We shut the doors, but my dad kept the 99. It runs great right now, except it needs a turbo up pipe. My mechanic says the whole cab has to come off to change it. I got a qoute from a dealer to change it and it was scary. Most reliable truck we had was a 2000 F250 with the 5.4L we bought new.

Noone said it was a major problem, but multiply that number by the 500,000 v10's out there and you have a common failure. That is the point of this whole thread, was to give the guy a heads up. He might run into it, he might not. But now if it does happen he knows it can be fixed.

Yup. I knew that it was a fairly common occurrence with the 5.4. From reading here it would appear to happen, but on a much less frequent scale with the V10. As you state, if it does ever happen it can likely be fixed without bankrupting my business! :laughing:

1999 F250 SD V10, blew a plug at 80K, put in a insert. No other engine problems other than cruise control. Just changed plugs at 215K, insert came out with the plug and I didn't notice it took a while to figure out why I couldn't get the new plug to thread. I like the V10, seems to be durable, I have the 5 speed manual and sometimes would like more gears. I think I can pull most anything, but it will not be at speed in these mountains. Mileage is fairly constant 12-13 mpg no trailer, 9-10 with any type of trailer, 2000lb box or 10000lb gooseneck.
