I bought this Expedition in Sept. 19’ with 120,000 miles. The Carfax was clean and showed all of the maintenance required and oil changes at at least every 5K. I had read reviews on various sites including Consumer Reports saying this is a great engine with the potential for 250K.

Before buying I had my mechanic check it over and everything seemed great. No codes, leaks or obvious problems. Brakes were good, tires new, etc. Interior is great, little wear, everything worked.

During our test drive period (had for three days,) the HVAC fan got wonky, had them upgrade to the new harness and it worked (and has worked) fine since.

We had a flashing check engine light the day after we bought it and took it to our mechanic. Showed a misfire on cylinder one. We called the dealership that sold it to us and they told us to bring it in. They replaced a spark plug and that solved the problem.

Five and a half (10,000 mi) months later, we have a misfire on one and four. My mechanic says we need a new engine, quotes $8,300 or so. Call the dealer that sold it to us (sold “as is”, they owe me nothing), they gave us a loaner and took it in to look at it. They did compression check (looks bad), valve draw down (still looks bad).

Service rep calls me (this is a Chevy dealership we bought it from,) and says they can’t go any farther. Says he has an ol’ buddy at the Ford dealership, 20+ years with same dealership,etc. I tell him to have ol’ buddy call me. After a conversation I agree to have them look at it.
Original dealership agrees to take it over there for me. Was the beginning of the Coronavirus scare.

Ol’ buddy calls late the next day, has bore scoped the cylinders, 6 has scoring. Need to replace the engine and a turbo. $10,300. I mention that my mechanic can replace the engine for about 8k. He says “let me see what I can do.” Calls back 15min later, new engine and turbo (includes tubes, etc) for about $9,000, maybe a little less.

Picked it up about 7-8 days later, just a hair over $8,700.

We are not rich, my wife is a nurse and I am an electrician. This weighs heavy on us (especially in this time of Coronavirus,) I went on unemployment this week.

My advice to new (used) buyers would be, have a compression check done on these engines no matter what. Any recent plug replacement could be a big warning. If you are starting to get misfires over 100k, look out!

Regards,
Josh

Was it the turbo that failed and sent shrapnel through the engine? Cylinder scoring bad enough to need a new engine on an engine that got regular oil changes sounds like it ingested dirt/metal. How about the air filter and air box and piping? All good and not breathing unfiltered air? Sounds like premature wear to say the least. But what caused the wear?

The Ford dealership that ended up replacing the engine did say that “the turbo that was bad was drinking oil”. I’m not anywhere near a mechanic, so not sure what that could mean.

Maybe someone drove it like they stole it.

I would just check all pipe and air filter box connections to be on the safe side anyway. If it was something as simple as breathing in dirt then you wanna make sure it doesn’t happen to your new engine. Hell, something as simple as a rodent nesting in the air filter box could kill an engine quick. You don’t have to be a mechanic to check that. Good Luck with your new engine, hope your gremlins are all gone.

Having watched multiple YouTube videos at this point, I am thinking of add in a catch-can. Not sure what happened here, just trying to save others. Have seen multiple posts about misfires...

FWIW, we love this vehicle. Just bad luck? Not sure, felt like we did our due diligence. Could happen to anyone, just throwing our experience out there for others before they buy. Do a compression check before buying! May have kept us from buying this particular one.

After replacing a plug and it ran better is no indication of anything. Very few people do compression checks before buying and it's not always going to tell you a whole story anyway. I think something got in there or it ran low on oil and I am wondering also if it really needed to be replaced. Dealers are replace happy anyway. Sounds like a bunch of bad luck but I would have driven it until the motor fell out before just replacing it. No knocks, oil burning, etc,. I would have just carried on.

I will certainly second that the shops especially dealers throw in the towel way too early and what to sell you a replacement engine. Independent shops do the same thing as they don't want to risk they're being another problem after they do work to it or I come back. They feel confident that a remanufactured engine is going to be good to go and if there is a problem it doesn't reflect on them at all but the company I sold the engine like Jasper Etc.
We have had several post recently where people were told they needed an engine when they simply had a cam follower off or messed up and 1 cylinder dead. This can happen and not even damage a camshaft and be a simple fix. The hardest part is getting the valve cover off!

Catch can is a must. Check out JLT passenger side can. $150. Also, full synthetic oil changes every 5-7000 miles. Plugs change every 30k and gap em to .030. Ecoboosts love to ear plugs. Run 93 if you can

I change my plugs every 30k also. That 100k mile range (or whatever it is) is ridiculous, they start wearing from day one just like tires when you drive the car our out the tire shop. It's hard on the cop's when you leave them in too long also.

It is very hard on the coils and that's what makes a lot of them fail before they would but 30,000 is probably being very proactive about it. With modern ignition systems from the early 90s on you are fairly safe to go at least 50 or 60 thousand miles.
This does depend on the type of plug but is anybody actually using plain old copper plugs anymore?? I had on occasion but you want to change them by every 30000 because the Gap Lee Road quickly. On a standard Motorcraft or Autolite single Platinum you can go 50 or 60 thousand and probably only a road the gap 5-8 thousands.
A double Platinum is going to wear even less. Irradiance would last even longer but I don't pay the money for those. There's also a trade-off on actual spark performance. Every time you get the harder materials that last longer you get less actual spark or you get a pinpoint spark that isn't exactly the best thing to promote the best combustion but in reality it's all kind of a moot point.
Nowhere ever did anybody decide that it was a really good idea to leave plugs in a hundred thousand miles... This was simply done so the manufacturers could claim you didn't have to do a tune-up for a hundred thousand miles. Buy our new high-tech engine in our new car and you will save money on maintenance and repairs.
Just like the new Briggs & Stratton push mower engines that say never needs oil changes just check and top off. If that's not a bad idea. Nothing is. All marketing.

I am all for buying used but buying a 4 year old truck with 120k miles not a chance in the world would I roll that dice.


But you’re well passed that. Find a local mechanic that installs Jasper rebuilt motors.

You should be quite a bit cheaper than 8k. Jaspers come with a 3 year/100k mile warranty too
