Helicoil makes inserts for plug thread repair as well, They still kinda suck compared to the more expensive alternatives!!

Why didn't you just leave the plugs alone, especially given the known problems these engines have with inadequate threads?

Believe me, I hesitated for a moment and considered this, but then I thought about what a PITA it is to change the plugs on these when the intake is on, now it is all open and accessible. This spark plug hole in question was loose when I took it out. If I just left it, I would have been stuck on the side of the road sometime in the future with a blown out plug. I would rather deal with it in a controlled circumstance now.


Why would a blown out plug leave you on the side of the road? I've driven V8's with seven and even six working cylinders. Not ideal but will get you home. And is there something special about this truck that you want to spend so much money and effort on? You can buy them on Craigslist for under $2000 all day long.


I was with you until you wrote under $2k. Try $4K for anything in decent shape with low enough miles to bother with, or else be in the same boat soon enough.... granted you might negotiate down closer to $3k.

Anything under $2k for a full sized SUV is a mechanic's special at best unless you live in BFE or get lucky at an auction.

Yep. It has to be REALLY bad on gas to go for that cheap, usually early-mid 90s throttle body injected OHV V8. Anything with port injection is going to be JUST fuel efficient enough for a young kid with no bills.

A low mileage, low rust SUV is going to have awesome resale near any large city.

Just to clear the confusion regarding why repair vs get another, I like my truck when it works. I know what it is, I have maintained it, I have serviced it, I have repaired it, I know the repairs that I have done and I feel like once I have this behind me, I will have a good running, relatively dependable vehicle back in service. I can't imagine why I would go from a vehicle that I have had for 10 years and know it's history, into a different used vehicle that I don't know the history. If I have these issues with my truck, what's to say a different vehicle wouldn't have the same issues coming down the road.
I fix it as it needs fixed and will continue to do so until I could afford to get into a newer vehicle.
As stated before, I thank those who have contributed awesome support to help guide me through my repairs and to help me make good educated decisions and repairs.

I didn't know that, is it one of these cheap under $50 kits that doesn't cut the seat just a reamer tap?

This is the "black hole" of owning an old vehicle on it's last legs that many of us have experienced. One keeps throwing more and more money and time at it with the thinking that "once I have fixed this problem, since I have already fixed almost everything else that can go wrong, it will be good for awhile". This is almost never the case with an old worn-out vehicle. Vehicles are far more complicated than many people think and something else will ALWAYS go wrong. There is a point in every vehicle's life where it is time to stop pouring good money into it and put your hard-earned money into a newer vehicle instead. I have been following your saga with this rusty old Expedition for awhile now and IMO this truck has reached the point of "time to replace". I know what you are thinking, "I have already spent so much time and money on it that I hate to give up on it now", just consider this experience a "lesson learned" going forward.

Don't cling to a mistake just because you spent a lot of time (or money) making it, they say.

Been there, done that, the Barchetta in my sig, used to have two...it started as a project vehicle, and the engine is running so well I spent a lot of time and money trying to make the body and interior decent. Now after a while I'm just fed up with it...and I must have spent 3 times what the car is worth.

Sometimes it's hard to draw a line and stop.

As has been suggested by a few posters, you either double down and go into the rabbit hole once again, or say enough is enough.

If enough money in labor and parts is spent, most vehicles can live on practically forever.

I don't know, I kept my old 930 going for 20 some odd years and never thought about the money I had in it. It was super reliable for the whole time. You are right though, dealing with old cars long term can be frustrating but somehow rewarding in some ways. I wouldn't consider getting rid of my old Beetle even if I had to rebuild it, I just like it.

I saw one that bdCardinal recommended as well for 250.00.
These could potentially be done with heads on.
I could have someone who has Timesert kit do it for less than 100.00 if I could get him the head.
Question is, how much more work is it from here to get the head off and back on (in my driveway). And would I be needing any special tools?
Trying to decide which way to go with this.
I do plan to keep the vehicle.

I have a 98 F150 4x4 with the 2V 5.4
Although I never tossed a plug in 150K, I pulled the motor out of mine with the body still on, it kinda sucked to do. I bought a FRPP short block and built a Lightning motor for mine.

I was able to find some 8 thread (spark plug hole) heads to do my swap with, they were only made in 03/04 but you can still find them. Your heads are NPI and anything 99 and up will be PI heads, you could swap on some PI heads and intake and pick up about 30 HP...or just timecert the one hole and be done with it. I'd but a cheap borescope to ensure the cylinder is cleaned of metal following the repair.

Even when I was a kid working on cars 50 years ago - Pull heads -and off to the machine shop they go. They'll give you a good guy price - or have your in-town mechanic send them there for the good guy price.

Who is comparing it? Just saying if someone wants to keep it and repair it so what they will all need repairs at some point.
