    Ford not starting (might be relay)

    I would normally be happy to point you in the right direction, because the exact same thing happened to me....but the mods will delete my post....so maybe ask Yupster?

    1 year ownership experience

    Congrats and glad that you are happy. I have a 17, bought new for $53.9 otd including Md 6% tax....I know things are different now though...I have 162K on mine.....I had to replace the spring hinge on the center console.....it's been flawless.

    Spark Plug Boot Seal?

    Spark Plug Boot Seal?

    The oil, in my case. The leaking seals allowed the oil to fill the spark plug tube and shorted the plug so it didn't fire. Feeding raw fuel into a cat converter makes a heck of a lot of smoke! When I asked a Mercedes dealer, they gave me the same blank stare.....so I fixed it myself!

    Spark Plug Boot Seal?

    Looks to be the edge of spark plug tube seals, typically embedded/installed on the underside of the valve cover then pressed/pulled in when you tighten the bolts of the cover. I replaced them on my 2.3Supercharged Mercedes. When posts "go missing":, many won't bother. If a vehicle sits...

    Spark plugs and coil packs 2017

    Thanks Loki, your timing is perfect. With 159K on my truck and the most recent plug change used 2nd tier plugs due to backorders, I needed new plugs....and here you are! Thanks again Brother, hope all is well! jeff

    Who has the World's fastest Expedition? Me?

    HDSteve.....I've always been curious about something and have gotten different answers over the years. Let me give you a bit of background. When I got old enough to start messing with machines, it was with my friends and we mostly had boat engines and their first cars, 5 or more year old...

    Eco boost mpg

    This was so funny I had to log on to respond.....Chucks been around a long time..... Just back your foot off the gas, ALL THE TIME brother.....LOL...... In both of my old expys that had the 5.4, they got 13.5mpg overall. The 3.5 will *hit & git it if I ask it to, I just don't......like hardly...

    Eco boost mpg

    Lazy man’s oil change…

    The oil filter is by far your weakest link. Leaving it in is a grave mistake, especially on a Turbo or supercharged engine where blowby is larger part of the equation. These filters are 1/2 size of the old PH-2 filter used on the 5.4's. They have very little holding capacity for dirt and will go...

    Random Misfire Detected

    The 2017 Expy is a very nice truck............you didn't go wrong OP. Your coils and plugs fail first under load and at 85K, it's time for both...you got the early warning flags! LOL I would have done plugs and coils as Loki said, yeah the expensive ones and as Train says, leave the muffler...

    Who has the World's fastest Expedition? Me?

    That totally sucks Steve! Really sucks! As far as the paint goes, yes a good painter will make you look at the door and say "where did he paint it" I restore and collect vintage bikes and had a NOS tank with a 1" chip in it. I dropped it off to LRC triples since I was going up for a wedding...

    Getting ready to buy - Is it an OK time?

    This is an Aprils fools thread, right guys? No one is really serious about buying a possibly-non-ISO-chipped, defeatured truck, for at or above list price, are they? No, this is a horrible time to buy, for a dozen reasons.....but we all gotta do what it is that we gotta do.....I won't fault...

    Who has the World's fastest Expedition? Me?

    Steve, You remind me of a friend from the SLK boards who did the some innovative things to the supercharged SLK. I'm not knocking your ideas or your enthusiasm.....but you could have selected 100 engines better suited to building. I build very high performance two stroke engines and when I do...

    Intermittent rough idle

    FWIW: in both of my V8 expys, I experienced rough idles..............really crappy idles......running your hand under the vac lines on the passenger side of the engine, there is a 90 deg bend in a 3/8 or 1/2" line, the heel of the 90 rests on top of the valve cover and well, melts over time...as...

    2012 Ford Expedition does not crank (not the battery)

    Since the censorship began, I rarely login but your issue is the relay in the passenger side relay box. I forget which # it is but it will be obvious, it happened to me with identical symptoms

    Water pump?

    Maybe someone forgot about the head issue causing head gaskets blowing in the 5.4 2v? I owned two of them, 380K combined mileage...I would never brag about that engine. It wasn't bad if you were gentle b/c of it's weak lower end insert bearings and head leaks on the rear, drivers side of the...

    A warning…

    JExpedition07, Really sorry to hear. For those that don't know, JE is one of the sharpest guys around when it comes to the 5.4, period. He does his own work and knows more than I ever will.....take his word as bank. Some of you guys know that I build two stroke engines.....very atypical two...

    Significant Repair - Only 28,000 miles - Rear Differential

    Thanks guys, good to hear from both of you guys! ..........they teach critical thinking in schools now, but the level they teach is what we considered normal for a 3 year old 50 yrs ago. Use your heads guys.............stop taking everything at face value. The line between believing...

    Significant Repair - Only 28,000 miles - Rear Differential

    Mine began making noise at 35-38K. I was told "you need to replace carbon clutch plates in the rear end". What I did was to replace the read fluid with Mercury outdrive fluid along with 4oz of the Ford modifier because I'm not stupid. (Marine grade lubricants are typically far superior to...

    In for cam Phaser noise

    That's actually the preferred old-school method Flybry but many modern engines are fabricated with minute` oil passages which will not allow flow, cold, of higher visc oils. The GT engine may be different and have larger conduits. Folks used to use Lucas oil treatments or STP...simply...

    In for cam Phaser noise

    Yup, You are right, I don't know anything but I seriously doubt that you are being truthful about using Mobil 1.............I have seen simply too many engine failures to believe you. Course YOU have the issue and after THREE trucks, I never have....but I get how some folks are just smarter...

    In for cam Phaser noise
