I think he's referring to the mechanic friend mentioned in the first post.

I was, Thank you.:thumbsup:

If you google and read the instructions for "Time Sert" repair tool kit it says that the tool set covers Ford 4-6-8 and 10 cylinder engines from 1993 thru 2004.
Now that is a flat learning curve!
In 2005 Ford went to a two piece spark plug. While they stay in they are prone to carbon up and break off when trying to remove, BUT they don't blow out!
If you have ever heard one of those engines being driven with the plug blown out it has a LOUD whistling sound.

My Grandson bought a Super Duty with a plug blown out for half book value. The seller was told it would need a new head. Probly by the mechanic mentioned at the beginning of this discussion. I hauled it home for him. I sat in the shop and drank one Beer while he worked on it. Truck fixed. Sold it the next week for a $2000 profit.

Unfortunately when the plug blows out it takes the coil with it that must be replaced along with threading a helli ? coil into the head to hold the new plug.

I just swapped a Ford F150 company truck with 329,000 miles on it for a Tahoe another guy didn't like (long funny story). The Ford still runs strong and uses a quart of oil in 4,000 miles. That's when I have the oil changed, so I never had to add oil between changes.

It has the small 8 with the plug problem. It spit two plugs so far. I don't recall what the mileage was when they went, but it if it's important to someone I can check the records. Both happened less than 15 miles from the office and the truck could be driven. It made a lot of noise and smelled awful, but it ran OK on the remaining 7 cylinders. We have another truck that lost one plug about two hours away from home base.

Repairs were with the helicoil-type kits and done by vendors. First of mine was at a local garage at nearly $1,000. Second of mine was about $500 at a different local garage, and the remote one (which was done by a Ford dealer, by the way) was $250.

I trust this will not happen with my 2016 F150 with a 5.0 L?

Had a 94 f150 straight six that kept spitting the last plug. First time it happened thought the motor was done for. After the 4th time a little jb weld and it has never come out. This was a rusted out beater that was never gonna see a new spark plug though.

Correct. This is the 5.4L engine that is affected. They built three different generations of that engine, and gen 1 is the one that spits out plugs. Gen 2 went to a two piece plug that won't spit out, but has a tendency to snap off when being removed sometimes due to excessive carbon build up at the tip. The Gen 3 version of the 5.4L doesn't suffer from either of these issues.

we have several of these trucks that we use daily if you have the 5.4 you WILL have spark plug issues not IF you have spark plug issues and yes they will partially blow out of motor we have a truck that did this on 2 plugs this year my truck last year showed code for miss fire in coil to plug this was not my first experience with this issue and ford knows its there but because the mileage is mostly over 100,000 plus before it shows up ford does not see issue with engine also had customer that has a van with same motor it went bad and the tools for rebuilding motor yes the tools are over a thousand dollars he went and bought crate motor i have a government account that has about 250 of these engines is service run problem goes straight to dealer or surplus sale and by the way ford dealer on my truck for plugs labor and 1 coil pack was 1200.00 dollars and 2 days work if any is interesed DORMAN HEAVY DUTY has tool kit for removing plugs without breaking them

If it's got a 5.4 V8 in it, RUN!:thumbsup:

I understand the 2v dont have near the problem of the 3v.

Good to know, Roughshod, thanks. I just got my (2016) 5.0 last month, and I would not like to have to worry about such a problem!
