#144 of 163 Ford F250 super duty. by carguyryker Jun 06, 2009 (6:28 pm)
Hi,   We have a 2000 Ford F250 crew cab, short box. It has the 6.8 liter V10, and man does this thing have power. Low end torque is through the roof for a 3/4 ton truck, especially for a gas engine. And it tows like no other. We once pulled a stuck 32 foot motorhome, with a 22 foot Malibu wakeboarding boat ataached off of a gravel boat launch. The truck crawled right out of it. The gas mileage is about 10-12, but if you want a gas truck that can tow this is it. It pulls our 3500 pound boat around like its not even there. The four door crew cab is great. 3 people in my family are over 6 feet tall, and we can all ride comfortably on long trips together. The truck now has 86,000 miles on it, and we have never experienced a problem, but as said before, it is maintained very well. Overall i would highly reccomend this truck.

Replying to: gysgtg2000 (Nov 28, 2007 10:24 pm) Howdy-   Newby here who just bought a 2006 F-150 Supercrew with 5.4 Triton motor about six months ago. It's got around 50K miles on it now. AFTER I bought it, there appeared several signs in the service dept claiming that "owners of 5.4 Triton motors between 2004 and 2006 should speak with service manager".   The service manager told me that they were aware that if you wait until 100K (the normal service interval for a plug change) that the plugs could seize or break in the heads, causing VERY expensive procedures to be done. He offered to change my plugs for $170.00   His recommendation was to replace them before 60K, thus preventing the problem. I have looked around the web and seen multiple horror stories of people with this motor having plugs blow out of the heads, break, etc. and now am paranoid about the whole situation.   My wife wants to go visit family in Maine from here in Texas in the truck this summer.    My question is this.......should I go ahead and have the plugs changed NOW and hope they follow correct procedures from TSB 08-7-6 which clearly shows how to remove the plugs without breakage, and hope that they can do this without screwing up and ending up charging me for plug inserts, or at worse, new heads? Or should I just keep trucking, and hope the spark plugs don't pop out on this long trip?   Any and all advice appreciated.   Mike Selvey Nacogdoches, TX Replies to this message: tnt102704 (Jun 08, 2009 9:52 am) notlob (Jun 08, 2009 10:35 am) mickeymouse2 (Jun 09, 2009 12:50 am)

Replying to: amborider (Jun 08, 2009 7:07 am) Mike, I recently had the plugs changed in my 2004, 5.4, at 65,000 miles, based on the some of the same stories you mention. I suggest you start using Lucas Fuel treatment with each fill up. This will burn off most of the carbon build up on the stems of the spark plugs. My service manager advised that the carbon build up is the source of the breaking/stripped plug problem. I bought the truck with 60k on it and had been using the Lucas to boost fuel mileage. When they changed my plugs (the $170 is just the labor, the plugs are another $80) only one broke off. In discussing this with the service manager, after the fact, he stated that the Lucas is probably why they only had a problem with one plug. I would suggest you take your trip, using the Lucas, and have the plugs changed when you get back. Beware, they also "sold" me on a fuel filter and injector cleaning, bumping my tab over $600, but on the trip to Daytona from W. Ky., right after the plugs and "cleaning" I got 21 mpg, loaded with 4 passengers and the bed filled to the brim, with my wife and her bff doing the driving. Both of them were hammer down all the way down and back. Good luck.

Replying to: amborider (Jun 08, 2009 7:07 am) I just talked with my service tech today at my dealership. Took my 04 150 5.4 3v in for a throttle valve problem. He had changed out my plugs last week and five of them were busted durning removal. he showed me the plugs (new) and now I can understand how they could be broken after they have been in the engine for some time. Plugs are normally good for 100k. , but the carbon build up would be very heavy long before 100k. Using Lucus Fuel treatment would help burn off the carbon build-up. Unscrewing the plug is not the problem, it's the extended tip of the plug that freezes in the alum head. A tech that's knows his trade can remove the extended tip without damage to the head. Take your trip, I have driven my F150 up to Wisc. many times about 2000k round trip and up to Ny a couple of times. I enjoy the trip in the truck over a car anytime. Notlob

Replying to: amborider (Jun 08, 2009 7:07 am) This is true about the Ford V8's and the spark plugs. The problem is not that the origial plugs blow out, it is when they are taken out the first time the carbon on the plug thread damages the spark plug thread. For what ever it is worth, when taking the plugs out, loosen 1/4 turn then retighten to break off the carbon from the old plug. Increase the amount of the turn each time by a 1/4 turn until you have made one complete turn, then remove. Napa sells a replacement spark plug that has a longer thread on it and goes deeper into the head. By doing this I havent had any of the new spark plugs pop out of any of the V8's I have done.

Replying to: mad17 (Jun 23, 2009 7:05 am) If it is that big of a deal getting a CAT. Just remove it and put an extension tube in there in its place until the part comes in. The down stream O2 sensor will set a code of poor CAT efficiency, but who cares! Your truck will still run.
