#1761 of 1953 Re: Spark Plugs [klbyrkit]
Apr 30, 2008 (8:18 pm)
I own a 1997 Expedition that had the #3 cylinder blowout. Ford has an unadmitted problem with the 4.6 and 5.4 liter Triton V8s. 1997 to 2000 are the early model heads that tend to show the problem at higher mileage. The 2001 to 2003 models are the "romeo" heads and have the problem over a wide range of mileage (as early as 40K miles). After 2003 I believe Ford used heads with regular length threads on the spark plugs but you should check with a Ford dealer to make sure that the Triton engine in the model you're considering has long thread plugs and not short thread plugs.
For those who have this problem, Ford dealers charge a wide range of prices to fix it. I've called half a dozen Ford dealers in my area and no two were the same. Prices ranged from $800 to $2000. On the lower end, most of the dealers are using a threaded insert repair. There are many kits on the market specifically designed for Ford Triton V8 spark plug thread repairs. (Just goes to show how common the problem is) Helicoil, KD, Lisle and Timesert all make kits. Ford dealers tend to use the Timesert threaded inserts because of two unique features http://www.timesert.com/html/triton_repair2.html . First, Timeserts have a positive locking shoulder. The bottom threads on the insert also lock in place once the drive tool is used to locate it. Other inserts suffer from backing out or in and blowing out again. Of course, there's no guarantee with the Timesert either and the dealer won't warrant the work. I've heard that one Timesert fix has more than 90K miles on it and its still holding.
I'm an accomplished mechanic so I ordered my own Timesert kit from an Ebay supplier (about $400). If your head is repairable the dealer will typically install the Timesert without removing the heads. If it's not repairable then the dealer will typically recommend a new head (lots of $$). The non-romeo heads generally are repairable. The romeo heads have an additional shoulder that requires a bigger reamer and a shoulder cut. The service tech told me these heads tend to be the ones replaced more often. I'll be tackling the installation on my 97 Expedition this weekend so I'll post a report after I'm done. But, if you're comfortable around and engine bay (and have a step ladder to work on an Expedition) you can probably fix this problem yourself.
One other thing to note is that the coil pack gets damaged when the plug blows outs. Typically, the tap that hold the coil in place breaks off. Since the coil itself still worked fine I epoxied the tab back on the first time this happened and its held just fine. If you're not into this kind of fix you'll have to buy a new coil pack (also expensive from the dealer - near $200)
If you have a mechanic repair your blow out then make sure they use the Timesert inserts for the repair. This will give you the greatest chance at longevity afterwards.

#1764 of 1953 2000 Expedition fuel problem
May 23, 2008 (9:52 am)
I have a 2000 Expedition that seems to have fuel problem. Especially when I am driving at higher speeds or going up hill, it acts like it is running out of gas. I put in a bottle of Lucas injector cleaner but the condition seems to be getting worse everytime I try to drive it.
I am wondering if anyone can enlighten me about what I can expect the auto repair shop to charge for this and what is the most likely cause of this condition. The 'check engine soon' light came on and off for a day or so and now it is staying on. A couple of weeks ago I ran it out of gas and this problem started after that, so I am thinking it is a clogged fuel filter or clogged fuel injection system.
The car seems to otherwise be running really good and strong. There are no noises, smells or gauges pointing at anything else suspicious.

I took my Expedition in to the mechanic and he saw that there was a leak in a metal coolant line that seemed to be leaking water on the spark plugs. He changed the spark plugs and welded the metal coolant line and the car is running a whole lot better but not perfectly. It still seems to have a fuel problem. I am not sure if I have two problems, one fuel and one with spark plugs that were corroded, but the problem is a whole lot better, just not completely resolved.
#1766 of 1953 1999 Expedition: Engine Stutter, Low Gas Mileage
May 29, 2008 (12:17 am)
I am the original owner of a '99 Expedition XLT (4.6L 4x2) and the car has been great except for the past six months. Has 126,000 miles.
Main problems recently:
- engine stutter/miss (intermitent) between 40-60mph
- transmission fluid leak
- thumping/moaning/creaking (from rear) when backing out of driveway and going over speed bumps
- very low gas mileage (averaging 11 mpg even with 1/2 of miles on highway)
I recently had it serviced:
- for engine stutter/miss: technician couldn't replicate problem in test drive, but they tightened drive shaft linkage and the problem went away for a couple of weeks... now it's back.
- for transmission fluid leak: replaced gasket at torque converter and driveway leak went away, but now I can smell that sweet scent of tranmission fluid burning off again just a few weeks later.
- thumping/moaning/creaking from rear end: have not checked into it.
- low gas mileage: have not checked into it.
I have read many postings from this website about IGNITION COIL PACKS and REAR DIFFERENTIAL problems.
Do the symptoms I describe sound related to these types of problems?
Can low gas mileage be caused by these types of problems? Or should I expect 12 average mpg from a 9 year old large SUV?

#1768 of 1953 Starting problems with the key and Theft device
Jun 03, 2008 (6:56 am)
Our 99 expedition won't start with the key from time to time the theft lights go on and it won't turn over, someone told my husband to start it three times real fast and it'll start, it worked, until yesterday, it won't start at all. What could be the problem?

I have a 97 and had a similar problem. It took a bit of investigating to identify the intermittent problem for me. First the dealer suggested trying both keys to see if I had the same problem as sometimes the key needs to be replaced. That was not it. I noticed that sometimes when it happened, it was not exactly on Park and that if I shifted into Neutral and back into Park it would start. They checked it out and found a screw/bracket missing from the shift cable assembly as I recall. They fixed it and I have not had the problem since. I am not sure if this was related to the TSB issued .
