Ford doesn't offer an optional engine in the Expedition. Sales are around 40-50K per year. So that is 200-250k engines. I have not heard the f-150 version having major issues, like the Expeditions. The EB's engine reputation is already sketchy. They are on the 3rd generation and still having issues. GM's Tahoe/yukon optional 6cyl is a diesel.

I was including the f-150 sales in the general count. I know expy’s sale are well below 1 million, probably over the last decade, even (including NON EB expeditions).

Your assuming the engine used in the F-150, is the same to the Expedition. They may use different phasers, cam shafts, compression ratio, turbos, exhaust, heads, blocks, pistons and oil pans. They may be built at different plants. There was 5 versions of the 4.6l. The 2v SOHC, 32V DOHC the 3V SOHC, The Romeo and Windsor. The engine used different heads, cranks and even valve covers

Glad to hear the warranty company is not giving you any hassle, makes the world much easier.

I also would like to jump into a 4th gen, problem is they don’t look good till you hit Limited Stealth or Platinum. Need to let the used market settle down.

One of the issues I have is that Ford made the heavy duty tow package optional on the 4th gen, instead of including it on the Limited and higher trims. I definitely need it. Not sure how I'm going to hunt one down.

I've had good experiences in the past with Fidelity. They paid for a rear main seal and some other work on my Honda Odyssey previously. Each time I've purchased the warranty it has paid for itself.

Agreed on the lack of engine options on Expy’s. I typically plan way ahead and for a while now I’ve been considering what my next daily runner needs to be. I know it won’t be an ecoboost and really want to avoid VVT v8’s. I know I’ll blow through those in 100k miles then need cam phaser job etc.

I’m averaging 800 mi week right now in 90 heat doing 75mph-80mph all highway w 230,*** on the clock now.

I’ll probably look for a pushrod style rig. I’m not convinced these VVT‘a will hold up to this type of use and give me 250k miles of trouble free engine and drivetrain.

Does your current Expedition have the HD tow package? I see you do a lot of towing and that creates a lot of extra heat ( especially in Texas) , if I had to guess I would think that had something to do with the head gasket failure. Did you ever see the coolants temperature spike on a hard pull? Towing in extreme temperatures is very taxing on things. Maybe even add more auxiliary coolers to help with temps.

I wouldn't buy one... Where's the benefit?
The benefit that I love is diesel like torque at low rpm’s. I think Ford got it right on this package especially for towing. I compare it to my pushrod V8 351W in my F150 which I’ve changed the factory 3.54 gears to 4.10’s and it still doesn’t have enough balls towing because it’s still not in its powerband for torque. Oh and I bought the truck with 68,000 miles on it knowing I had to put a engine in it due to no oil pressure and rod knock. I didn’t know the history of the truck (auction) but new I could put a Ford remanufactured in for $1,800 my cost. It’s all about maintenance and abuse for the most part.

Sounds like a job for a diesel.

Yes, it came with the Heavy Duty tow package. I've done very little pulling up grades and never saw elevated engines temps. I purchased it with approximately 58k. The tech said no warpage to the heads or deck so if anything happened before I got it it must not have been severe.

This is why I’m thinking I’m going to stay with another Expedition and get the 3.5 EcoBoost/10 Speed over the 5.0. I like that my 5.4 3V has all its grunt in the mid range so it doesn’t have to scream up revs when I tow. I can let the tach sit at 3 grand and she will pull anything uphill....I think the 5.0 needs to hit 4 grand or higher before it meets what the 5.4 3V puts down at 3 grand.
