  1. I just wonder if the 7.3 gas V8 engine will spawn different displacement variations? Maybe a 6.6V8 and an 8.0 liter V8 for heavy duty truck applications. The 6.6 could completely replace the current 6.2V8 Also, an. Aluminum block 7.0 V8 might be possible for Mustang and Light truck. Applications. (107.2mm X 97mm) Does anyone know the bore center on the new 7.3V8? Some time ago I Suggested 117mm but That was a guess looking at the blocks in the Windsor engine plant annex. Probably very close to the old FE series V8 of 4.63”?????? edselford
  2. I just wonder if Wayne Assembly will be producing three different BOF vehicles not just two? It seems to me that the T6 platform includes the Ranger pickup, Everest SUV and the new Bronco. There is a real market for the Everest in this country, off road capable, larger than the Edge but smaller than the new 2020 Explorer. The Bronco could fit on a modified frame with a unique body. so is there going to be three distinct vehicles at Wayne assembly? I do remember Wayne building the second generation f150 based Bronco their and the F150 many years ago EDSELFORD

    Wayne Assembly

    It probably makes sense to Waite until T6 is upgraded and market stabilizes before Ford considers an Everest/ Endeavour for this market. By then however, we may be in a sea of SUVs from every OEM given the profit potential versus regular sedans! I just like the toughness and durability of a Body on frame vehicle and the north/ south architecture which make the inclusion of low range possible! (Use of transfer case) edselford
  4. Dear sirs why would you not offer the 3.3 liter V6 naturally aspirated engine out of the Ford F-150 as an alternative to the base 2.3 liter eco boost? I am sure such a drivetrain with the ten speed would be smoother at low engine speeds than the 2.3EB please advise edselford
  5. I have a 2016 Taurus SEL with all wheel drive and 20” tires. Vehicle purchased in June 2016. I have driven the vehicle 49,000 trouble free mile with only oil and filter changes. Todayvehicle started making very bad smell coming thru the heating system . Something like a natural gas type smell not a gasoline smell. Checked for antifreezes leak and nothing is leaking or missing. No gasoline leaks. Had to drive home today 15 degrees from river view to Brighton mi with heat turned off and windows down. Also smell just as bad standing next to car. Does anyone have any ideas what could be causing this thanks edselford
  6. Thanks YT90SC that looks like about $2000! We go thru design cycles every 15 to 20 years where a new group of engineers motivated by magazine car writers think that changing car architectures is the better way to go! went from double wishbone front suspension to. McPherson strut and now back to modern day double wishbone. All wheel drive from transfer case on demand to PTU with in line coupling and now back to transfer case active electronic control! New is not always better! edselford

    2020 Explorer with 3.3 NA V6

    Well interesting discussion. I did not know police and fleet can order 3.3 NA V6 in 2020 Explorer. why? A segment of the customers would prefer simplicity and long term durability. I’m sure sound cancellation technology used to cover up some nvh issues due to 4 cylinder. I have had two ecoboost engines a 1.6 and 1.5 liter in escapes. They feel great at lower engine speeds but run out of steam above 70MPH. also my 2013 Ford Taurus fwd with 3.5 liter and 2.77 final drive got better highway mileage than either ecoboost engines. its interesting for me with all these turbos because in 1983 I participated in a study at Borg Warner to determine if the car companies would need turbo chargers for future downsizing! we said a definite yes but we did not have the timing quite right. The first Borg Warner turbo designs were based upon IHI designs made in Japan. edsel ford
  8. I finally got back from Florida (used my wife’s Escape! picked up my 2016 Taurus from the dealer. They replaced the PTU completely! Two teeth were missing from hypoid drive gear. And I’m not really too hard on my car since it’s not an SHO but just looks like one. this must be a common problem with Taurus/ Explorer All Wheel Drive vehicles. thankfully, vehicle’s 60,000 mile drivetrain warranty covered the repair cost. Does anyone know what I would of been charged out of warranty for the repair? thanks edselford

    New Ford 7.0 L....?

    Ford could of easily expand the 6.2 V8 to 7.3 liters. There are many reasons they did not. I think they needed a gas engine for the F450/550/650 that made the most sense ie lowest cost, lowest frictional losses, best low end torque and best fuel economy for intended duty cycle. If someone wants a V8 at about 7.0 liters, for mustang, it would probably be a dual overhead cam version of the 6.2. The question always is can the financial results justify the investment and resources given the SC 5.2 V8 availability. Also, both GM LS gen 1 through 5 and the new ford 7.3. Engineblock archetectures look allot like the old Buick 364/401 V8 engine block! edselford

    New Ford 7.0 L....?

    All very interesting info and discussion on the new 7.3 V8 and the GM 6.6 V8. The design looks like a bulked up 351 W with added technology of variable valve timing at much wider bore centers with GM LS heart shaped combustion chamber. Mary you are right about machined slots between cylinders! We did that on current Chrysler FCA 3.6 liter V6. Great way to have stronger block and H2O where you really need it! Ford FE and original Chevy 2.8 V6 had narrow cylinder heads that had cooling issues because of lack of water passages in critical places. I’m sure ford would not make that mistake again in new engine. Actually ford went backwards when the Lincoln Y block was discontinued. 4.63” bore centers, and they tooled the FE andMEL! also, expect a smaller version of the new ford 7.3 to eventually replace the 6.2 doc V8 some time in the future. edselford

    New Ford 7.0 L....?

    Well, a 4” bore and 4” stroke gets you to 402 cid or 6.6 liters. based on experience with first generation small block in cast iron, no need for wider bore centers. Expect higher deck to around 9.8” to have acceptable r/s ratio. edselford
  12. Thanks sorry I was off a little but I would suspect the 75W140 is used because the PTU is not large enough to hold a quart of fluid and torque is continuously transferred to rear thru coupling causing very high PTU temptures. To avoid failing the hypoid and other gears they have to use a 140. edselford
  13. Guys thank you for suggestions. Car is an all wheel drive. 15W-150 gear lube used in PTU and rear differential. because smell surrounds the vehicle when engine off for extended periods of time, probably not leak but I will check! I realized what smell was like yesterday. 30 years ago When I worked for Borg Warner selling the T5 manual 5 speed to Ford for the Mustang GT. mustang at the time had a tremec 4 speed manual overdrive transmission. we built a Mustang 302 V8 a hi rise intake, marine cylinder heads Holley 4 barrel carb demo vehicle. It took one ride by Bill Ford himself to approve the program. I built many T5’s in that time and lube used was first gear lube that smelled like the Taurus problem I have now. Thirty years is a long time ago! It’s at the ford dealer waiting to be worked on since it’s not drivable with the smell. so probably PTU related. Dealer just called. The entire PTU needs replacement. Wow now I know one reason ford is switching to rear wheel drive based Explorer. This must be a common failure with current Explorer/ Taurus AWD not enough real estate to do a PTU correctly! Guys thank you for your help. edselford

    New Ford 7.0 L....?

    If you work thru the annual volumes for chassis cab, F150 thru F 550 and assume slightly lower diesel penetration than today, working the numbers results in approximately 140,000 annual volume for the 7X V8 engine program. This would.include a 7.3, a 7.0 and a smaller 6.3 liter version of the same basic design. Think Chrysler B and RB series V8 and you won’t be too far off! edselford

    New Ford 7.0 L....?

    Excellent question! If 7.3 liter V8 has same architecture as the 6.2 V8, bore centers would be 115mm. It would need to have a taller deck height at around 10. However, if the 7.3 is a completely new architecture, I suspect the bore centers will be increase to around 117mm, close to the old FE series of the 1960s. With 117mm bore centers, we would have enough room for water between each bore with ample wall thinness for a couple of overbites in the reman business. Deck height would be around 256mm to allow for a heavy duty piston compression height and say a 1.63 rod to stroke ratio. If we take this same block and utilize a shorter stroke to get to 7.0 liters, the con rod would get longer and the piston compression height would get shorter giving us something around a 1.76 rod to stroke ratio. This is how you can have a 7.3 HD and a 7.0 HP from the same block! Unfortunately, no one is taking yet so its all speculation on my part! Edselford

    New Ford 7.0 L....?

    Any new information on the new 7.3 V8 gasolineengine? The video of the Prime Minister of Canada at the plant seems to show new 7.3 V8 engine blocks that are longer than the current 6.2 V8. This would indicate an increase in bore centers from 115mm to something around 117mm. If it is a push rod design, expect two cams in block! One cam for intake and the other for exhaust. I could easily see. 7.3, a 7.0 and possibly a 6.277 versions over time. Appreciate any inputs Edselford

    10 Speed Auto

    Yes, they are basically the same designs. Ford looked at third gear, 3.01 and realized third was too close to 2nd so they eliminated the 3.01 ratio and made their third, 2.45, which is gm's 4th gear. Overall ratio spread is the same between GM and Ford, 7.56 to 1 so top gear is the same at .62 to 1. There is a little of this in the Ford/GM Ten speed rear wheel drive design too where one of the gears is really too close to the ratio of the gear before it so the step is less in the middle of the range than at the top end. I guess, the way the ECU is programmed, it may just skip the gear when not needed. Edselford

    2020 Explorer

    I saw another Engineering mule on Tuesday night at about 5:30 pm on the Dearborn streets. The Explorer prototype, if this vehicle was it, is a little longer than the current model and silightly wider! Again, I payed much attention to the underbody of the vehicle, and again for the second time, I saw a frame under the body! Maybe its a C section frame from the engine craddle/front suspension to the C section side rails. I tried to get a look at the front suspension but was not able to. Don't know if it is a carryover McPherson or a double wishbone?? Edselford

    2020 Explorer

    2020 Ford Explorer? The prototypes I have seen in Dearborn driving down Oakwood Blvd. near the Oakwood Hospital look like a Body on Frame vehicles because there appears to be an actual frame beneath the body. Vehicles look very similar to the current Explorers, but the current Explorers are unitized and Front wheel drive based! I will guess the new Explorer is slightly bigger than the current, built off of a modified Ranger/Everest frame, ie wider and longer, and rear wheel drive based! This is not a step backwards because if you do it right, the weight penalty is almost zero, more flexibility, easier restyling etc. Actually GM had it right on the old rear wheel drive intermediates, I think they were called G body , Regals, Tempest, malibu, cutlass supreme Body on Frame and balanced structual stiffness between BOF and Body Structure! If I am right, and the 202 Explorer is rear wheel drive based, you will able to get a four wheel drive Low range in this new vehicle and some type of active all wheel drive for high range. Every thirty years or so, we make the full circle on vehicle archetecture. Pretty soon we will have a New Lincoln Towncar! Edselford

    2018 Taurus??

    New Taurus I'm on my second Taurus, first was a 2014 Taurus SEL FWD. Current is a 2016 SEL AWD. Both nice vehicles. I do like the handling of the AWD better than the front wheel drive. Also no torque steer with the 2016. I think you should not expect any changes to the Taurus before the Explorer is redone for 2019 or 2020. This is because both are built at Chicago Assembly and go down the same line. I have driven many Fusions, current model year and they are nice but the width is what stopped me from getting one last year. When the Explorer gets redone with added wheelbase and revised powertrains and transmission 9 speed, you can expect something to happen with the Taurus in terms of significant update. I do not think the Taurus will ever be like the Chinese version. Edselford

    New Ford 7.0 L....?

    I agree, current V10/ 5.8l V8, 5,4l V8 are at 256mm deck height! I would maintain this dimension on a new 7.0 liter V8 plus or minus 2mm. Its like what can we machine on the existing cylinder block line???? LIkewise, on the new 4.8 liter V8, Ford could keep the current 227mm deck height of the 5.0 liter/5.2 liter V8's or make an adjustment up to say 233mm to 237mm, utilize 93mm stroke and have about a 1.67 to 1.70 Rod/stroke ratio instead of their current 1.62. IE make the 4.8 a truck engine! Edselford

    New Ford 7.0 L....?

    Both 7.0 liter V8 and a 7.7 liter V8 could be made from the same block with a 10" deck height. Much easier than dealing with balance shafts, crankpin breakage issues due to a 90 degree V10. 105.6mm bore and 100.2mm stroke gives 7.0 liter V8. 105.6mm bore and 110mm stroke gives 7.7 liter V8. out of the same block! edselford
  24. My wife has a 2014 Front Wheel drive Ford Escape with the 1.6 liter Ecoboost engine. the vehicle was purchased new in October 2013 and has 32,600 miles on the odometer. one week ago after a scheduled oil change and tire rotation, the vehicle started making a humming noise from about 15 mph to about 80mph. The noise varies with vehicle speed in frequency and is a constant drone type noise at constant speed. At lower speeds, it sounds like a bicycle with a baseball card attached to the fender rail, that hits the bike spoke to create a noise when we were kids. I just don't understand what is going on/ I checked the tires for nails and punctures and they are all right even though they are the original, 20" wheels. Does anyone have any ideas what could be causing this noise, that seems to come from the back of the vehicle? Thank You Edselford

    2014 Escape humming noise at road speeds

    I had Ford dealer in Brighton drive vehicle over about 18 miles. Conclusion was that when tires were recently rotated, the front tires rotated to the rear were somewhat cupped on outer side and this was making the noise. Dealer checked for wheel bearing and it was not a wheel bearing noise and not related to engine/turbo issue. Well, continental tires were rotated on a normal basis, either 10,000 miles, every other oil change, or 8,000 miles to the current mileage. How do tires get cupped? edselford
